Definitely, but then, call it what it is. "Tech" companies are those who provide "tech" products, such as cloud hosting, software for managing tech stacks, etc. It's not merely "anything that requires software to run".
You have a point: Apple is developing its own hardware and even recently switched over to designing and manufacturing their own components. There's something of a spectrum here (are air quality sensor station producers "tech" if they're just soldering other people's components onto PCBs whose designs were farmed out to consultants?) so it's not so cut and dry but you can probably safely say that if you're designing your own CPUs you need a significant amount of tech expertise.
