Win 10

Can I upgrade win 7 32bit to win 10 64 bit full version

You cannot even upgrade win 7 32 bit to win 7 64 bit.
Changing from what system architecture to another requires a clean install. An upgrade is not supported.

What you can do is:

Upgrade from Windows 7 32 bit to Windows 10 32 bit. Get the activation code. Then clean install Windows 10 64 bit.

Or

Clean install Windows 7 64 bit with the activation code from Windows 7 32 bit. Then upgrade to Windows 10 64 bit.

I can only advise that, the last time I did what you are describing I was able to clean install Windows 10 using my Windows 7 Product Key during the install process and it worked perfectly fine.
I cannot say if Microsoft has taken steps to prevent this with the most current version / build of Windows 10 as my attempt was performed a month or more ago with a different ISO.
I will add that the "upgrade" process is no longer free so a clean install is required.

IF your licensing options include a second device, then I don't see an issue at all, but....
I think, if I had a second "new HDD" to test with, I would probably try the first option to see if that would allow a clean install with the Win7 product key before I sacrificed another product key.
