Yes, but whereas the AK-47 and the AK-74u are visually quite different one being considerably smaller than the other, the AK-12 and the AK-47 are visually very similar. Same applies to the M4A1 and the M16 (discounting CoD4, where they both looked visually similar). They could work around that, I guess, but it's probably something that they'd rather not do.

Plus, on a side note, CoD tends to opt for weapons that people have heard of, with a few exceptions. Hence, they've put the AK-47 in plenty of games despite it being old and dated, purely because it's the world's most famous firearm.
