You can, you will just need to bypass the fuse check by booting into RCM and sending a payload that doubles as bootloader and bypasses the fuse check (aka Hekate, ReiNX, SX OS V1.2+), However if you put a console into a sleep mode while it is running a firmware lower than the fuse count, then you will be unable to wake up from sleep mode.
