I only skimmed that article, but I don't see anywhere it says 40 hours is optimal. I only see where it says every hour beyond 40 is harmful:

"By the eighth hour of the day, people's best work is usually already behind them (typically turned in between hours 2 and 6)."

It sounds like 30 hours might well be optimal, but has simply never been tested.

You're right. Good point.

Actually it has. See Kellogg's 6 hour day

That looks like it's about round-the-clock shifts for factory workers. I can think of a lot of differences between that and, say, computer programmers that might render the conclusion less relevant.

For example, I don't know any software companies in the world that build software with 3 8-hour shifts of workers.
