Under FIDE rules nobody can, bot even an arbiter/trainer/second or...parent.
Remember Karpov - Kasparov W.C. 1987. Kasparov forgot to press his clock,
Karpov never told him. Karpov won taking advantage of Kasparov's time trouble
though to be fair Karpov was in the better position.
Nobody has to, ok,
Maybe arbiter is not even allowed.
But it is a part of sportmanship to tell your opponent.
Chess is not all defined. Great deal of sportmanship consists of unwritten rules.
I don't say he had to do it.
I am saying he is no gentlekid when he didn't.
And I will continue to tell that to my opponents if they forget to press the clock.
