Not only you cannot, but you are not supposed to have two accounts if both are in your name, though you can have one personal and one business account for yourself.
No, you can't transfer between two accounts. It is possible to have 1 business account and 1 personal account, as previously stated. My company ran sites and when it closed in December 2010, we closed that adsense account, but it was tied to a limited corporation and the revenue stream went there. You will get your 2 accounts banned if they are personal accounts if you try.
Why you asking this question if you already guess the answer,... or maybe you can ask google and let us know here,. lol
