Of course knowledge is a word that can be defined in many different ways. Depending on your definition, you'll get different answers. In this case, yes, knowledge is generally considered to be synonymous with absolute certainty. So I advise using that definition in regard to these terms. But there is always room for debate about that. I am absolutely certain no omnipotent god exists, because it's logically possible. I'm not absolutely certain a floating teapot doesn't exist though.
As we've already discussed though, the meaning of agnosticism isn't defined by its etymology, like most words aren't. The meaning of agnosticism is not "without certainty". but a round-about way of saying "i don't know enough to form an opinion either way", or "its impossible to know enough to form an opinion".
