It all depends on the ratings the commercial pilot posses on his certificate. The FAA requires a type rating for all aircraft above 12,500 lbs. Type rating is just additional training required to become proficient on a particular aircraft. If the commercial pilot has the right categories and ratings for a particular airplane, they can fly it.
It depends on your type ratings. The biggest plane you can fly without having aircraft-specific ratings on your license is a plane with maximum takeoff weight of 12,500 lbs and without jet engines - turboprops are fine. It just so happens that the plane that exactly meets these requirements is the King Air 200.
If you have type ratings for the biggest plane in the world, you can fly the biggest plane in the world with a CPL.
