Yes you can, you can change officially via Odin or install custom recovery and flash whatever rom you desire. I got my S4 back last year on o2 then flashed the BTU (unbranded UK version straight away) and now run the Google Edition rom. However I am on the bootloader and can flash whatever I wish without tripping KNOX but only via CWM.

What current firmware are you on?

Be aware as you have a KNOX bootloader installing recovery will trip this and you can't reverse it.

KNOX when tripped can cause issues with warranty. Now as we live in the UK we have warranty covered for 2 years by the EU. But it's like a warranty flag they could use that against you and not fix any issues, it will also disable KNOX which is a security feature but more for commercial rather than personal and it you will not be able to downgrade your firmware.

You'll be able to go back to whatever stock rom you were originally on or higher. I suggest looking in the android development section for the pre rooted roms, I think there are ways to flash a custom rooted rom without recovery without tripping the knox flag.
