No, the radiant heating needs to go under the wood floor. Because you have forced air heating, I'm assuming you don't have a boiler, so you'd either have to add a boiler for this -- probably not a good investment -- or use electric heating mats, which work well. You'll need to take up the floor, though. Here's a link with more info.
A better option might be to just add a baseboard electric heater in that room -- double the heating and some extra cost, but much less than tearing out the floor.
