Now, if your new Battle.net account has the name First Name, Surname, Date of Birth and Country of Residence as your old one - which presumably it would, yes, you can ask for your new licence to be moved onto your old Battle.net account. This will carry over any achievements you've earned on characters on the licence you're moving over, any mounts you've earned, but pets will not move.
It can be done through live chat or a phone call. As long as you're the legitimate account holder of both, and you have a form of Government Photo ID and possibly your CD keys, it won't be an issue.
