It should be fine. Some foods are particularly good at picking up smells and flavours from the air, but that's mostly really porous stuff, not chicken/pasta. That's also usually more applicable to raw stuff sitting in cupboards/fridges together for several days, not stuff that's being cooked for less than an hour. The only really strong smell/flavour in there would be the garlic, and it's not impossible that you might get a hint of that in your mac & cheese, but it won't be enough to be a problem (that, and garlic in mac & cheese isn't necessarily a bad thing).
