I'd tile behind to be future proof it as you may not get the same tiles (or fan model) in say 5 years time.
Thats why the chimney stack part of most extractor hoods (above the actual unit) are extendable/movable to allow for change of actual hood unit in the future.Thats how mine works and I only had the splashback tiled up to below the hood itself and then fiinished off with a chrome edge.
You dont need to take the thing off the wall at all,waste of money and tiles too,pointless.
