No; Piccolo just massively grew strong enough to destroy a moon; or are you going to question as well that DBS Goku can destroy the universe now whereas he was at best galaxy lv before?
Besides, Piccolo busted a country.
"Will", "could", "would have" - these things, purely based on speculations, do not matter at all in a crossover battle.
Otherwise I can claim as well that Naruto god tiers will reach universe/multiversal lv at the end, FT characters will destroy entire solar systems, MHA characters having their own multiverse at the end and so on.
Bring facts, not speculations.
