Hard disagree. Knowledge and intelligence are inextricable because the way that humans learn advanced concepts involves a lot of thinking and reasoning.

You don't just learn by ingesting facts from a book line by line. You learn by reading a little, then pausing to think, building connections with other things you know, rephrasing the information, deducing the unwritten parts, finding patterns, fleshing out the contrapositives, being critical, etc. This is especially true when learning advanced topics.

I would say learning is more about information processing than information uptake. That's why more intelligent people learn faster. The linear prose of natural language is actually a terribly lossy way to serialize and transmit the knowledge that is in a person's brain. The receiver must deduce most of it given a small seed.
