Can characters on the same account be split

[Alawen Everywhere]

So I made a ranger on the same account as my druid just to fool around with the class and be able to track two places at the same time. Over the months, I happened to level him up to 45.

Now an old friend of mine from live is interested in playing the ranger as long as he doesn't have far to 50. We were thinking about joining one of the casual raiding guilds together. Is it possible to have this character moved to another account or did I screw the pooch by starting him on the same account?

Thanks in advance for any word on if this is possible and if so how it's accomplished.
