Summary:: The Poincaré group and M-theory both have 10 dimensions

Is this a coincidence?
Yes. And there isn't even a defined single dimension for an M-theory, since there are several different concepts unified in M-theory. In any case, M-theory generalizes string theories, which involve super Lie algebras. The Poincaré group has a classical Lie algebra and moreover isn't semisimple.
