Short answer: Not unless something very strange is going on.

Long answer: the problem is that the planet would have to be significantly more massive than the star. What makes this a problem is that stars work by their own mass pulling the star together via gravity, so anything bigger than a star *becomes* a star (until you hit the limit for black holes, anyway). For a planet to be big enough thar a star could orbit it, you’d have to have some mechanism in place to prevent the planet from turning into a star itself. I’m not sure we know of anything that can do that.
