It is just semantics, related to philosophy, but not astronomy. Planets do not even orbit around sun, but center of gravity which is outside of sun.

The barycenter (center of mass, not gravity) of the solar system can very much be within Sol's limb. For all intents and purposes the planets do orbit the highest center of mass which is within or at least very close to the surface of Sol.
