From what I found online, Twitter restricts you to 1 account per email. They don't care which email goes with which account. So if you are certain you are never going to create a personal account, then I guess you could go ahead and use your personal email.

However, this is all based on what I found online. I cannot guarantee the accuracy of this information. If you want to know more about creating Twitter accounts, it would probably be best to ask Twitter's official support team.
