You can in fact.  Just not with Grub.
There are other boot loaders that can do this just fine.

(And then again, you can even sort-of do it with GRUB, if you use it
in combination with an able boot loader.)

Smart Boot Manager is one of the options:
http://btmgr.sourceforge.net/about.html

It supports booting from ATAPI (and PCMCIA) CDROMs.

If you feel like coding something up yourself, the source code for
Smart Boot Manager is available.  If you are in fact loading your boot
loader from a CDROM also, have a look at ISOLINUX, which is a
particularly excellently coded piece of software that makes use of El
Torito.
