It is theoretically possible but is likely to break on many systems.

To boot it from a raw disk (the normal operation for Syslinux) would
require a small amount of software which currently doesn't exist, but
you can test it using a disk image and using MEMDISK:

kexec -l memdisk --initrd=disk.img --real-mode

If this actually works and is useful it would be a quick hack to add the
missing piece.

This will not work on UEFI platforms; there is no way to revert to UEFI
boot mode without a system reset.
