Knox is like secureboot with PC it creates a chain of trust from bootloader up to ROM. If anything of this chain is modified Samsung will not feel responsible for any software related bugs or software security concerns.
Hardware warranty is lost only if the manufacturer can prove that your software modification resulted in damage. Over clocking or playing wih thermal threshold are such cases. Rooting or flashing is not..
