I think that kind of depends on how big your lap is - I can work on 15" MacBook Pro just fine, while sitting crosslegged.
And of course also how big the laptop is with regards to screen size. For example, modern Dell XPS 13 has 13.4" screen but is narrower than 12" Thinkpads of old.
And there's a big jump from 16" screen in a MacBook to "desktop monitor" which in modern office probably would be 27" 4k display.
