Yes. In fact, you can stack two ships on the same tile too. But keep in mind that damage inflicted on a tile will apply to all ships on that tile. So, if the enemy does enough damage, they can destroy both of your ships in a single shot. Considering that cannons can often do 200-300 hp damage easily, that can be enough to destroy both ships if they are stacked. So, stacking can be risky.
Also: Don't stack fighters on the same tile as your permanently-cloaked ships. That's just asking for trouble.
