They sure can. It's quite rare though, and only happens when there's something disgusting in the tank (Dead fish) or if the water conditions are bad enough.
Their form of vomit is a white substance that they eject from their rear, and it lingers in the water for a while before being sucked up by the filter or settling on the bottom.
Once again, this shouldn't happen often.
This depends on how much you feed them. Normally they can excrete quite a bit when being fed the proper amount of food, but when over fed, goldfish can decorate plants in your tank with poo garlands like a Christmas tree.
It's best to not over feed your fish.
