Can I "upgrade" my old 32-bit IBM ThinkPad to 64-bit by installing a new hard disk? I am running Ubuntu 14.04 but want to upgrade to a newer Ubuntu system. Can Anyone help this novice with that?

You can determine if your computer's CPU is 32 or 64 bits by running
sudo lshw -class processor | grep width
If the answer is "width: 32 bits" neither replacing the hard drive or installing another operating system will transform your computer into a 64 bit machine.

If the processor is 32 bit, you can't do what you're trying to do, otherwise it's absolutely possible. Since you have a pretty old version of Ubuntu I assume the hardware also old. So even if the processor is 64 bit, your system might get slower with new versions of the OS. You'll have to find a slimmed down version of Ubuntu derivatives which supports older hardware. You can still find 32 bit versions of Ubuntu flavours but slowly the support will be limited to 64.
Hope this helps!
