It depends on a few things. First of all, suppose the Wyrmling gets hit with an Ennervate, and loses some of its RHD. Now suppose you hit it with a Greater Restoration. Would you say that it's ineffective, because it would cause the Wyrmling to gain levels?

Another thing. Would you say that losing RHD causes a dragon to move back age categories? If so, no dragon should ever die of old age. If not, you could age your Wyrmling and give it the powers of its new age adjusted for the lack of RHD. No levels gained.
