@Anon: Considering how big Tenrou Island was, the Tree would have to be really close to the guild (or the other way round) for that to matter. The distance between the center of Tenrou and the coast is less than what used to be the distance between Magnolia and the ocean after all.

But thanks to Universe one it is a possibility that the guild hall ended up far closer to the coast and thus possibly near enough to the the new position of the new position of the Tenrou Tree to be in it's protective aura.
