If an effect such as <Decoy> prevents deletion when this suspended Digimon would be deleted, can I use this card's [All Turns] effect to unsuspend this Digimon?

No, you can't. This card's [All Turns] effect is triggered when one of your Digimon with [Chessmon] in its name is deleted, therefore it won't trigger if such a Digimon isn't deleted.
