No, as well as being warm blooded, mammals are characterized by the presence of sweat glands, including milk producing sweat glands, and by the presence of: hair, three middle ear bones used in hearing, and a neocortex region in the brain. Also all mammals, other than the monotremes, give birth to live young instead of laying eggs. Most mammals also possess specialized teeth and utilize a placenta in the ontogeny.

There are other warm blooded animals that do not posses these characteristics, e.g. birds and the great white shark. It is also evident that many of the dinosaurs must also have been warm blooded. Yes, warm blooded animals are mammals because think about cold-blooded animals like snakes.
