It's more than a subtlety, imo. A distro is an OS, and linux is the kernel. An OS implies direct user interaction; the kernel runs the hardware in the background. Seriously, take a moment to explain the technical shit in a way that someone unfamiliar with it will understand - 'linux is like an engine, and distros are like the different vehicles that use it under the hood. Anyone can use it, and even change it, but Linus has final say on the design of the official engine.' Was that so hard? Even grandma can wrap her head around that.
