Nope, it does not recieve the boost from the ability Mega Launcher. The move may have "Aura" in the name, but it does not apply in this situation as the move doesn't seem to have an "Aura or Pulse." The move is just a wheel made out of some type of electricity, it would not make too much sense for it to be boosted. Another supporting reason could be the fact that in-game, Morpeko cannot have the Ability without ability swap or hacks. Only 3 Pokemon can have that ability and they cannot have that move in their set. An argument could be made that Kyogre's move Origin Pulse gets boosted and that Morpeko's should too but Aura Wheel is a Physical Electric type attack and has no reason to be boosted.
Hope I helped!
