Not in this case.
As Bramble says, CZ, or any other rifle manufacturer for that matter, not just implies, but explicitly states that their rifles are chambered for and designed for the use of a specific cartridge. If said rifle will not even chamber the round, then they have failed to deliver on their advertised promise. Not only that, but the BATF would have an interest that a manufacturer licensed to manufacture or market in the US has failed to insure the safe function of a firearm, which in this case, CZ obviously did fail to inspect the rifle for proper function.

There is an element of low cost - lower quality in play here, but that is not the same as low cost - inoperational and unsafe.

There should not be an expectation of spending a great amount of money to buy a fully functional high quality rifle. There are many guns on the market right now which will perform every bit as well as any $18-30K custom for well under $10K.
