Can you change this call?

[JEL]

H.S. playoff game, H.S. rules, Call went against home team, and happened this way; pass to 15 yard line, defender clearly hit reciever before ball arrives, in fact two flags were thrown for interference, reciever juggles ball, then catches and runs into end zone. Should be 6 points BUT...one ref blew whistle as reciever caught ball(inadvertant whistle was explanation to coaches), and possesion was given at point of catch. Defender had fallen to ground, and no other (offense or defense) player was within 20 yards of the play. Home team fumbled and lost 20 yards next play, never scored on this possession. My question is, Can a mistaken or inadvertant whistle be overturned? could the TD have stood? (official in end zone signalled TD). If in referees judgement, the mistaken whistle would have had no effect on play, can play stand?

This was a tight game, and this score would have put home up by 1 point in 3rd period. Home went on to win with a 4th and goal TD pass with 38 seconds left in game, so above call didn't factor into a loss, but I am curious as to what some of you guys think.
