It might have some crossover, but my guess is it's probably much more introductory than that book. I didn't know this until fairly recently, but Concrete Mathematics was used in a Graduate level course at Stanford as the textbook (with the course name following the book's, Concrete Mathematics). Kind of threw me off when I first found out, because the book says it's a foundation for computer science, so I thought it would be an undergraduate course. So, I don't think you need to be a graduate student or in particular a Stanford level computer science graduate student to read Jeremy Kun's book.
