It has been reported that, if you work with support on instances like this, they can often work something out.
I've never seen an instance where that was the case. The "trigger" seems to be hosting, not registering, a domain. Even if you did host it, you could avoid running afoul of this policy by simply making sure the "new" account was not created using a promo code. You could even make that part of the terms of sale of the domain, avoiding the issue altogether.
Again, if you have a particular issue, you should contact support about it and see what they are willing to do. I'm quite certain that if they are convinced that the move is not an attempt to "re-use" a promo account, they will find a way to facilitate you.
