Yes, it's possible ...

AFAIK bootable CD must fulfill El Torito
specification,
Short answer:

if on the addres 8800h  (17-th sector)
u will find string similar to: 
blabla ... EL TORITO SPECIFICATION
it should be bootable.

Long answer:

check short answer +
on address 8847h is a 4-byte pointer to catalog
of bootable floppy images (from specs CD can have
more boot images, like lilo or grub)
Pointer to first image is on addres 28h in the catalog.
Now u can find and analyze this image (or copy it to floppy)
and check if it is really bootable.
But to be 100% sure, burn it on RW and check,
on minimally 3 different PC's  if it not boots,
since there can be still bug in FW of CDROM,
bug in BIOS ...
