I think it depends purely on your definition of "tech". Impossible engineering soybeans to produce more heme to make fake meat behave more like meat is a technology, in that it is a novel innovation applied to solve a real world problem. But in modern common parlance "tech" tends to mean either that a company's offering is either entirely or heavily augmented by new software, or that the company has ties to a specific network of talent/investors/etc, or that the company has very low incremental costs per user. In those cases, they might not be a tech company.
