So I say YES. A mentalist can do magic routines, but not in the same context that he/she does mentalism.
For example. When I do mentalism for a certain audience, they do not see me perform any magic whatsoever. This is because, mentalism on some level has an "explanation" that is not sleight of hand, be it "real psychic powers," or "clever psychological influence." Introduce sleight of hand, and this is broken.
But say, seven hours later at a completely different spot, I can introduce myself as a magician. I can do it, and there is no law that forbids me from doing so.
