Are wonton wrappers also called puff pastry?

No, puff pastry is often purchased in the freezer section of the store next to the frozen pies and pie crusts. Puff pastry is painstakingly created by folding and rolling out sheets of dough with layers of butter so that when they bake the water in the butter creates steam and "puffs" the layers of dough, creating the soft, flaky texture that puff pastry is known for.

Won ton wrappers are more closely related to pasta dough I believe.
