First, icing can occur at temperatures well above freezing. Ask any pilot. At low throttle settings, air squeezes by the almost closed throttle plate, the expands quickly to fill the intake manifold. The temperature drops rapidly. This is the same method used to make air conditioner - take a compressed gas and let it expand. At the right combination of air temperature, humidity, and low throttle setting, you can get icing. Even with a warm engine on a nice day with the flowers blooming. By heating up the throttle body a little, it prevents condensation that can freeze.
At really cold outside air temperatures, there is usually very little moisture in the air, so there is no water to turn to ice.
Does it impact boost? Not really. That heat rise is negligible, at least compared to the massive heat rise from turbo compression. That's why there is an intercooler to cool down the charge. Yes, theoretically heating the TB a little will reduce max boost, but by such a small amount as to make no difference.
So, can you remove the lines? Sure. Chances are good you'll not notice any difference, ever. No improvement in boost, and probably no icing. If you're a full-throttle driving kind of guy, then you definately won't see it. But if you get cool, moist mornings (40 degrees, F, say), and drive on a level highway (low throttle settings for periods of time), you can develop icing.
My approach - leave it in. Just my opinion.
