It’s perfectly legal to install a 240v outlet. They’re most common for electric stoves and dryers, but you also see them for machine equipment in a garage or workshop, air conditioners, electric heaters. There’s no reason you couldn’t have one in a kitchen.
Finding an appliance to use it might be different. Not only would an appliance for another place be designed for different electrical system (eg 50Hz instead of 60 Hz) but there would be none of the typical certifications and it would have a different plug. Technically there’s nothing stopping you, but you’re probably past the threshold of plausible deniability.

That being said, it was tempting!
