Technically, yes, but a large number of people are working on tables that are already too high, so positive tilt is required to keep their wrists in line with their forearms. A laptop stand that elevates the laptop, placed on a table that is already too high, requires even more positive tilt. And don't forget the large number of people who don't know how to touch-type and need clear visibility of all the keycaps.
