Personally I'd ditch the rug, not the coffee table. My reasoning:
1) The rug takes up a lot of the floor space, basically right up to the edges of all the furniture. To me, it just doesn't look right without much in the way of a 'border' (empty space) around it. It dominates the floor space and probably contributes to the feeling of 'darkness'
2) Coffee tables are practical. We have a chunky coffee table in our lounge (taller than yours) and while it makes the room look smaller it gives us somewhere to put remotes, drinks, tablets, tins, paperwork etc etc. Rugs don't really serve much practical purpose other than protecting a carpet.
Overall your home has a good contemporary feel. The poster who said it looks cluttered would have a heart attack if he saw our house
edit: When I see things rooms this with no/minimal storage units (bookcases, display cabinets, chests of drawers, sideboards, cd/dvd racks etc), I wonder where the hell people keep all their stuff! [notwithstanding the fact that we have too much stuff, but that's another story]
