The Poké Ball (Monster Ball (モンスターボール Monsutābōru?) in original Japanese language versions) is a spherical device used by Pokémon Trainers to capture wild Pokémon and store them when not active

So the answer is no, because when a Pokemon is returned to the Poke Ball, it’s not active.

Another scenario is when traded Pokemon evolve, but only when they are called out of their Poke Balls after the trade as happened, e.g. when Bianca & Prof. Juniper traded Shelmet & Karrablast, meaning that they do not evolve in their Poke Balls because it keeps them in a stat of inactivity.

Poke Ball

In every episode I’ve seen, they always evolveout of their Pokeballseither battling or under extreme stress (like when J or Team Rocket come). Also, the Trainer would be too stunned to react if the Pokemon started to evolve. So, no.
