Install 64 bit programs on a 32 bit OS with a 64 bit processor
Is it possible to install a 64 bit program on a 32 bit OS with a 64 bit processor?
In principle yes, but the processor and the OS have to support it.

Is it worth reinstalling 64-bit Ubuntu instead of 32-bit on old hardware?
It won't be faster in any meaningful way, but the reality of 32 bit is that it's increasingly legacy, which means, in the real world, bugs are not getting found and fixed.

If amd64 packages work on your laptop, without QEMU, then it’s a 64-bit x86 system. The T6600 CPU is a 64-bit x86 CPU.
Note that 64-bit PCs have been the norm for over 15 years (arguably since 2006).

Well, 64-bit vs 32-bit does change the run-time memory usage somewhat, in that it changes the size of pointers. On amd64, an int (the default integer type) is still 32 bits, so that doesn't change. ...
