Sure, some businesses will employ more people if their income isn't taxed. But many others (especially in the tech sector, like you pointed out) won't. Apple alone accounted for 4.4% of all US corporate income ($72.67 billion vs $1.637 trillion according to Wolfram Alpha). I think more jobs could be created by using those taxes to fund e.g. infrastructure projects.
