Specialized Armadillo Tires allow for a lighter tube?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Since they are so puncture resistant, I could use a 70g tube with a 25mm/700c tire?

I suppose you could, but why? The main advantage of a thin, light tube is that it reduces the wheel's rolling resistance since less energy is lost when the tube is periodically compressed at the contact patch. But the stiff sidewalls of the Armadillo tires result in a high rolling resistance which dwarfs the contribution of even a thick tube

Doesn't much matter. Tubes are the least of the protections against puncture except in some very specialized, thorn-resistant cases.
