Not quite true. Chromebooks can approach MacBooks in some ways. Google mandates 10 hours minimum battery life for anything labelled "Chromebook", along with 8 years of software updates. That's competitive with Apple.
Chromebooks support crosini, which is a Debian installation. With crosini you are forced to use the ChromeOS "window manager" but everything else is standard Debian. GUI apps like Firefox, Gimp and so on just work. It still gets it's 10 hours when using crosini.
Most Chromebooks are targeted at the education market and so are very low end, but there are a few high end Chromebooks. They are amd64. In MIPS/watt they are maybe 1/2 of what Apples M series can do, so they can't reach the heights Apple does - but they come as close as the hardware allows. You will probably see a Snapdragon X Chromebook ... one day. On that day, Apple will find its performance and battery life threatened by a "Linux desktop", assuming you are willing to call Debian + ChromeOS window manager a Linux Desktop. Who would have dreamt it?
