The advantage gained from the check-n-go is minimal but there is no real disadvantage as far as I can see, so why not. This assumes that CO has a stack which make calling your all-in preflop a no-brainer - which of course means that, more than likely, calling post flop will be a no brainer too. But somewhere in there, there are a few combinations of stack size, holding and flop that might get a fold post-flop. There's also the slight chance that his cat will choose just that moment to knock over the lampstand and cause him to miss his chance to call...as I said - minimal.
