Yes, according to the film's Visual Dictionary the modified AT-M6 has specific defenses against the cable-wrapping attack seen in Empire Strikes Back. The front of the leg has lifting (sharp) cutting edges.
"Foot Mechanism ventilation gates also double as cable cutters"
This issue was also addressed in an interview with the film's Design Supervisor Kevin Jenkins.
One of the questions that tied us up a lot is the fact that they’d
been taken down by snowspeeders in The Empire Strikes Back, and it
felt like everyone else is trying to avoid the problem of a
four-legged version of a walker because they had been defeated on
Hoth. So I sort of took that on board and I suggested to Rian, “Well,
instead of a dog, what about a gorilla?”
The front legs are very heavily armored, and you can see almost up to the forearm. And again, that’s my take on, “You can’t take these down
with a snowspeeder.” They’ve armored up the front or maybe they just
cut the ropes because they are too big now. Also, the way they are
balanced now is like a gorilla, because their knuckles are turned
backwards and they’ve got very high shoulders. They are a completely
different poise. Maybe they could even sort of kneel down or
StarWars.com: I’m glad to hear that they finally figured out how to defend against tow cables.
Kevin Jenkins: Well, it was more of a thought process of trying to base the design not upon something random but to move it forward.
