Well, that depends on how you look at it. The Cox .049 was nothing more than a tiny diesel. So it would be correct to say that Cummins and Caterpillar and Detroit Diesel are making glow engines.
But on the scale of Cox? Probably not.
Not exactly. A diesel engine relies purely on compression for ignition. There are RC engines that work on this principal, but the cox .049 is not one of them.
Glow engines rely on compression and the heat from a glow plug for ignition.
Yes, most diesel engines do have glow plugs to make them easier to start, but once they’re running, the glow plugs are shut down.

According to Wikipedia, the cox .049 does work on this principle – the glow plugs are disconnected once the engine is running.
“The Cox .049 Engine is a 2-stroke internal combustion glow plug engine. These engines use a glow plug to heat the fuel/air within the cylinder to start. Once running it is disconnected and operates in the same manner as a diesel engine. The self ignition is due to the heat produced from the compression of the air/fuel mix, and the catalytic reaction of the platinum element and the methanol in the fuel and does not depend in any way upon the continued use of the battery or glow plug.”
