Not by regulation. Handling these is left to the TD's discretion.
I once had, as a player, a case involving (at teams) this hand: ♠AKQJ8754 ♥J32 ♦ - ♣ J6. Our opponent holding these cards opened 2♣. They got to ♠ via 2♣-2♦-4♠-AP. One of our teammates defending this hand said that he had misdefended because he expected declarer to have more high card strength. They made 4. We asked for a ruling. The TD said "it's almost a psych, but not quite" and let it stand. Unfortunately, I didn't ask him what small change would have made it a psych. Later, in correspondence with ACBL HQ, I was told that the GCC says this opening must be "strong" and that "strong" means "whatever the player making the bid thinks it means". That's not a paraphrase, it's a direct quote.
