On the old BIOS systems, if I wanted to swap hard drives on a system

Should I expect a UEFI system to do it that simply?
In theory, yes. At least I think so. :)
Your UEFI firmware has a list of boot devices and paths to a
bootloader. On each device, it expects a FAT filesystem, in which it
will find the bootloader at the corresponding path. If you "dd" a
drive, then all of the UUIDs for the filesystems should be the same, and
the system should boot without complaints.
If any UUIDs do change, the UEFI should look for /EFI/BOOT/BOOTX64.EFI
as a default. That file exists on your Fedora system partition, and
IIRC, it will add a new boot entry to the UEFI list and boot your Fedora
system.
And do secure boot options throw any spanners in the works, too?
No, it shouldn't.
