If the CD-R is on a controller RSTS understands (MSCP is the only
option I can think of for this) and is formatted with the RSTS file
structure, and has a boot block in sector zero, it should all just
work.
I haven't personally done this but I'm pretty sure it was done by one
of my friends. I even have some weird "hybrid file system" hacks in
RSTSFLX to let you create a CD-R that's partly ISO and partly RTST,
and bootable. I believe that was used and shown to work, though I
never saw the results.
If you have the files, RSTSFLX can make a bootable disk image for you,
so you can try this yourself.

I didn't have any problem with getting RSTS/E to start to boot off of CD-R,
where I had problems was with it not liking the fact it was on a Read-Only
filesystem. If I had a better understanding of RSTS/E, I suspect this could
be overcome. I've not had the time to look further into the matter.
