Boruto's case is different from the 1-st stage of Naruto's Chinin Exams. The true objective of this very stage was actually cheating without being caught. It wasn't even specifically forbidden, only limited to being visibly caught 5 times red-handed. During Boruto's Chunin exams, neither of the stages had the objective of cheating, while Kote was the tool specifically forbidden by rules. Of course, technically, nobody would've disqualified Boruto if he hadn't been caught, but not because he was masterfully hiding the use of Kote, rather because nobody payed attention to that at first.
