Is it possible to take a Centos 3.7 machine - that was installed with the 32 bit version of CentOS, and update it to a 64 bit kernel?
In other words - convert an i386 to ia64. I don't care about the applications, just the kernel.

Actually, it'd be converting i386 to x86_64. Converting from i386 to ia64 is one HELL of an upgrade. It's technically possible, but it'd be a world of pain. Far easier to reinstall.
So, that said, is it possible to upgrade x86_32bit to x86_64bit, or is it better to start fresh?
Boss just asked last week if I could do it, and I declined and just asked that the machine be wiped and made fresh...

That's the fastest, easiest, and probably the most reliable way to do it. Wipe and re-install. Make sure your old partitions get reformatted just to be sure.

Quite right. I mean to upgrade to x86_64 - not ia64

The problem is ... you would need all the other things that the kernel requires also to be installed in the x86_64 mode (pretty much most of the core and base groups from the install CD).
It would be much safer to do a new install ... though technically possible to create a chroot ... use yum to install x86_64 target stuff into the chroot and figure out what you need, then install that into the main root. I have never done this, but it should be possible.
