Probably not with the metal that exists in normal amounts in human bodies, and we haven't seen it.
Metalbending is a form of earthbending... however, when Toph first developed the ability, it was made clear that she wasn't bending the metal itself. She was bending the small impurities of Earth inside the metal. In essence, she was already doing what waterbenders do with bloodbending, only with metal.
This is why Platinum (in the Avatarverse) is resistant to metalbending, because it's highly purified and these earthbenders have nothing (or not enough) earth within it to work on. Of course the show has not entirely been internally consistent on various matters (mercury, for example, seems to be controllable by metalbenders despite it being a liquid and any impurities used to shape it more likely to be wrenched out, but maybe mercury, though a metal, is considered a form of 'Earth' that can be directly manipulated rather than the impurities within it).
In the human body, metal certainly exists... but it tends to exist in extremely minute form, basically atomic, and diffuse throughout the body. The metal itself is the impurity, and so to manipulate it you'd need to find microscopic impurities within already microscopic impurities and control them all to manipulate a person. Even if you could, you might be able to draw the metal out (which could well be fatal), but using it to control a person's body? There's just not a lot of structure there to do it, compared to bloodbending, where water is everywhere in the body (and waterbenders are already skilled at controlling free-flowing material).
That's not to say it could never happen, as metalbending itself was once considered impossible, but it seems to be far more difficult. And there are edge cases, like Suyin, Toph (and eventually Korra herself) attempting with various degrees of success, to control the extra metal within Korra's body from Red Lotus poison, or if somebody had, say, a hip replacement (so far unseen in the Avatarverse to my knowledge), the metal hip might be controllable by a metalbender who wanted to make them do the hustle or anything else.
