It's not your equipment, you didn't buy it, you can't just do whatever you want with it. It's like being given a company car but going on a 3,000-mile roadtrip "because why should I have my own car if you gave me this one?"
It's not remotely unreasonable to expect someone not to use their employer's equipment to make money on the side, especially for something like a laptop which over the course of what a developer earns in 4-5 years is basically nothing.
