This should be possible if the boot loader on the CD is grub, and you're
prepared to edit the boot command-line at boot time. Or prepare that
entry in advance by editing the templates, I guess.
I'm not exactly sure how to do that with syslinux/isolinux .
Or use a USB key. Most computers today can boot from one, though it may
be less trivial to set one up. The upside is that it is now trivial to
edit the configuration of the boot loader to point to whereever you
want.
