If you mean by inplace-upgrade, no.
If you mean by backing up data (carbonite?) and reformatting the drive, then yes.
However, will your system run amd64 Windows?
If your CPU architecture is 32-bit, you cannot run 64-bit windows.
What make and model is your CPU?
If CPU architecture is not 64-bit, you cannot upgrade to 64-bit version of Windows. 64-bit Windows require 64-bit instructions that are not present on 32-bit CPU.
Regardless of what processor ar architecture you have, you can not upgrade from a 32bit Windows OS to a 64bit Windows OS. You'll need to perform a clean install as long as your hardware supports 64bit, which it almost most certainly does (as others have stated).
