The first answer who comes to my mind is no. No, someone who doesn't have one point in the skill cannot have the technique by default. Especially for combat skills because combat skills don't have any default level! Even Brawling.

Having said that, I don't see why someone totally untrained couldn't try to use a motion picture camera if he can use a camera or try to hit someone with his elbow or his knee if he can try to punch or kick him ... The penalties are high enough to make the difference with someone trained.
