It would take A LOT more than that to kill Megatron. So long as a bit of his body remains, and there's some dark energon to help with the repairs, he can be rebuilt. (One of Dark Energon's powers is to bring Cybertronians back from the dead)

Zod's heat vision would atomize Megatron. Assuming he's about Superman's equal, he can use it to wipe out entire planets. That kind of fire-power would reduce Megatron to dust.
