Just because Chekov wasn’t on the bridge and we didn’t see him doesn’t mean that he wasn’t still part of the crew somewhere else on the ship. When we finally did see Chekov in Season 2, he at no point claimed to have just joined the crew.
This is how I make sense of it too. Kirk wasn't going to put some fresh face on the bridge without serving with him for some time first.

Either Ricardo Montalbán or Walter Koenig (I forget which of them used to tell this story) head canons it that Khan had to use the (never seen) Enterprise toilets after Ensign Chekov when he was still a lower decker, and Chekov had used the last of the toilet paper, which is why Khan burnt his face into his memory.
Khan didn't know own how to use the three seashells?
And so Khan probably would have recognized anyone he had seen on the Enterprise then, even for a second. Actual episode elapsed time can be hours or days so he likely saw most of the crew.

In case anyone is wondering, the actor says he didn’t say anything as that would reduce his screen time.
Not sure how true this is, but it’s believable.
Pretty sure Anton Yelchin and Benedict Cumberbatch were both in Star Trek: Into Darkness
