No.
That's maybe one kind of so-called cover band but it's by no means the nature or point of all such so-called cover bands or all such so-called covers.
It's completely feasible and reasonable to cover a song whether or not the audience will know it.
You can actually have an audience going 'That's a good song, who did you say wrote that?'.
Or more likely, they won't care who wrote it as long as it's got a proper tune, a hook or two, and maybe it makes you want to dance or at least tap a foot.

Agreed, one of our most popular songs is a version of Elvin Bishop's 'My Dog', which few people know. Especially as we play it in a different style and have re-written some of the words to suit a British audience. But it's definitely a cover.
