I *strongly* doubt it.  When you go from 32 to 64 bit systems, you are
essentially replacing the kernel and (at least) about 90% of the
standard libraries.  I am willing to bet that this mandates an
installation.

For the record, I've never tried it.  When I put CentOS on my machine,
I already had a 64-bit CPU and I never seriously considered NOT using
the 64-bit install.

HTH.
