Harry broke the Trio's protective enchantments when he said "Voldemort", do you think the same could have happened in Hogwarts?
You-Know-Who had a spell put up so that he would know whenever and whoever said his name. The protective enchantment for Harry focused on You-Know-Who not finding out where Harry was, and not so much on disabling any physical contact.
Basically, if anyone mentions You-Know-Who's name in Hogwarts, even if his spell is strong enough for him to detect the invocation, the defenses of Hogwarts are adequate to keep him out.
In a real world parallel: If my friend checks in on Forsquare in a nearby pub, I can go to him and beat him up for owing me 20 bucks. However, if he checks in at Area 51 military base, I can't, even if I know exactly where he is.
No, otherwise he would have done it a dozen times over whenever his supporters were in there.
The protective enchantments at Hogwarts were designed by resource experts to prevent exactly this type of thing.
It is like the big bad wolf blowing down a house of straw and then coming to a house made of iron, in a mine field, with several military trained piggies sitting at machine gun towers waiting to call in flying pig aerial support.
TL;DR No, I don't think so.
This is too long to fit as comment so I'm extending a little and making it an answer.
The magic protecting Hogwarts is a very different kind of magic. For the following reasons:
First of all the protective charms seem to hold even after the casters die. a) There is no mention of redoing Hogwart's protective spells after Dumbledores death, while the Fidelius charm protecting Grimauldplace did (sort of) fail. b) Having killed Dumbledore the Death Eaters still have to leave the Hogwarts grounds before they can disapparate. c) And the Chamber of Secrets also keeps its magic (e.g. need to speak parsel to enter) a round 1000 years after Slytherin died.
Also, in The Half Blood Prince Dumbledore mumbles in an odd/old tounge to let him and Harry fly over the walls. IIRC he doesn't even use a wand for that. Both is rather untypical for "contemporary" magic.
- Further, if we are willing to accept the movies as cannon, McGonagall say in DH Part 2 (something along the lines of) "His name is Voldemort. There is no need to call him you-know-who". I believe we can trust her to know if that had any serious consequences.
From that I would deduct there is a more solid kind of magic, one that endures more and longer than your ordinary swish and flick and there you go magic. If we can establish that such a stronger magic exists then it is safe to assume that over the centuries Hogwarts headmasters who have always been concerned with the safety and conceilment of their pupils have developed very sturdy protective charms. And to round it off: Voldemort was only able to put up the taboo once he had "the full power of the ministry" (whatever that is) at hand and given that at least Dumbledore has always been very eager about keeping the ministry, its powers, influences and even juristiction (e.g. unforgivable curses in HP4) away from Hogwarts, it is also safe to assume that the Ministry's powers do not reach that far into Hogwarts. Just count the educational decrees in HP5 that were necessary to impeach the headmaster after the fact.
Now, one may argue that all of this could have changed after Voldemort took over, but after Snape, an alleged Death Eater, had taken over Hogwarts it may not have been/appeared necessary to magically (as in physically) extend the Ministry's power to Hogwarts. Especially Voldemort, who (like Harry and Snape) felt very strong about Hogwarts (lost boys, first real home, etc., cf. HP7), probably never saw the necessity to change anything about Hogwart's foundations and may even have felt the need to preserve Hogwarts.
In that regard Snape and Voldemort may very well feel the same and since Voldemort knows about Snape's past he very like trusted Snape with about everything that has to do with Hogwarts. And there, Snape swore to Dumbledore to do everything in his powers to protect the students of Hogwarts, cf. another one of Snape's left behind memories. In that case Snape would have seen to it that the Ministry's magical (as in physical) power was kept away from Hogwarts, as it always had been with the previous headmaster(s).
