I just tried and it seems to work.
And I'm not doing anything illegal, since I own licences for both. Only the add-ons are only licensed for either EDU or commercial.
I wanted to avoid maintaining two installs (libraries, updates, templates etc...).
My corrupted license is a "known bug" with Snow Leopard. Needed to re-install and use the final serial directly instead of "re-activate".
