That's not necessarily the problem here.
Normally, Fedora would boot on both types of systems, too. However, OP wants to copy an already-existing UEFI install or at least the config to a legacy system, not (necessarily) to find a distro that could be installed from a normal live installer on both boot types.
Thus the Nix recommendations, as theoretically, one centralized config could be copied between systems to create a similar environment on different systems.
Definitely yes.
