No you cannot without formatting the drive and reinstalling

If you want to move from a 32-bit version of Windows to a 64-bit version of Windows Vista, back up your files and perform a clean installation of the 64-bit version of Windows Vista.

Also you have to be running 64bit hardware to have any benefit of going to a 64bit Operating System
