Deactivating office 2007 serial key and activating on another computer? - free serial key for mount and blade

My brother bought a laptop 2 years ago, with a license key for Office Home & Student 2007th He is currently studying at an institution which provides free office serial key. We've recently bought a new laptop. I would like to disable the product key on the laptop to my brother and use the new notebook. Is it possible and how can I?
