If the hobby involves something that the company does, listing it can indicate that you might be a more useful or versatile employee.
For example, if I was applying for a programming job working on the billing system at a company that does electronics, I could add a hobbies section to my resume and list there that I have an extra class amateur radio license.
That would let them know that I probably know something about electronics. That's not relevant at all to working on the billing system, but it would let them know that I might also be able to work on other programming tasks they might have that do need a knowledge of electronics (for example, working on diagnostics software for their service technicians).
