Harm? How? I'm not suggesting it'll work, 9 times out of
ten the OS can't find the boot drive partway through the
(windows) boot process unless you prep it ahead of time, but
I don't recall ever hearing of hardware damage from an OS
config, unless you mean something more rudimentary like
popping a DOS bios flash floppy in and having it auto-run
flashing the wrong bios.

If each system has an XP license, for same version of XP I
mean, it is not a violation of terms. Regardless, they
don't have the ability to blacklist the installation key
because they don't have a mechanism of automated collection
of such keys and blacklisting them. The keys they blacklist
are most often those circulating the internet in forums or
warez/pirated OS copies.
Regardless, if each system has a license for the same OS,
you can simply switch the key after migrating the OS image,
if it would work (if you prep it first for the different
drive controller/boot-volume location).

Agreed, the OS need not be exactly the same installation,
just a standardized test with benchmark apps that can be
installed per-system or ran without any installation, but
memtest86+ isn't a very good indicator of overall
performance, only a burst rate memory subsystem index which
these days with multiple channels of DDR2/3 makes less
difference than in past eras of slower memory.
