Yes, you can. It will work well outside. There are a couple of considerations, though. It's a good idea to keep the unit under a cover and not just "out in the air" on the back patio or the like. It isn't a good idea to expose it to sun or weather. UV light can damage the door seals, and you don't want the unit rained on. Keep it sorta clean and clear around the unit. It might present a haven or "hang out" for local critters like rodents or some insects. Spiders like fridges, too. The warmth of the compressor is a magnet to some of these and to other not-so-friendly neighbors.
