No, Pokemon cannot be traded in or out of a Mystery Dungeon series game to any other game. However, Pokemon that evolve by trading can still evolve in Mystery Dungeon by using an item known as the link cable, which is found in the game. I know that this item can be found in Solar Cave in the older Mystery Dungeon games, in place of the Hidden Machines found in the locked chambers.
