Technically, yes. Microwaves might interfere with wifi signals, though, so it’s not a great idea to place the two appliances close by if you have a smart TV or if you want to use web-enabled add-ons like Apple AirPlay or a Chrome Stick. There’s a reason microwaves have vents, too. They emit particles of food residue over time, which is why your microwave has vents and the areas around them get dirty over time.
