Not really. The hash would prevent someone to pull the rug unnoticed, but it wouldn't prevent rug pulling in the first place.

With a hash, you would be able to prove that what's currently at that url isn't what you bought, but (since hashes are by definition non-reversible) you wouldn't be able to show or see what it was you bought (unless you stored it somewhere else yourself).
