Default Note 10.1 v2 and knox

I'm looking to buy a 2014 10.1 and something caught my attention and was curious about it. I have a s4 running 4.3 android and thanks to Knox I cant put a custom recovery on it and have to use safestrap to use a custom rom essential wasting much space. Is that a issue with the tablet as well. Or is twrp/clockwork able to be used?
