Very good question. Most companies that started out from being supermarkets, fashion or restaurants who then have an app on the App Store and use tech made from FAAMNG companies now call themselves "tech companies" which they clearly are just are using them; thus are "tech-enabled".
Companies involved with both creating, producing or contributing to actual "technology" like CPU design, OSes, SDKs, compilers and toolchains which most of the FAAMNG and semiconductor companies do fit the definition of a "tech company".
