Can a receiving team signal a fair catch on a kickoff but kicking team catch it after it goes 10 yards not interfering with receiving team?

Yes, a receiving team can signal a fair catch on a kickoff, which allows them to catch the ball without being hit. However, if the kicking team catches the ball after it has gone 10 yards, it is considered a live ball, and they can advance it. The fair catch signal by the receiving team is only effective for their players; once the ball has traveled 10 yards, the kicking team is allowed to catch and play the ball.
