Don't cut the wire; it's almost certainly a factory-installed jumper. This sort of thing is very common in electronics. The euphemism is "ECO" or "ECN" for "engineering change order/notice." The common term is "fix for a screwup."

So, in the original PC board layout, there was an error (either of omission or commission), and the addition of the wire was needed to correct it. If you look at the board very closely, you may even see where another connection was Mototooled out of existence. It's likely that yours is a first-run board; later ones were probably laid out correctly, and therefore didn't need the fix.

If you open up lots of electronics, you'll see this type of thing fairly often. It's par for the course, given the crushing schedule pressures engineering teams have to work under.
