Yes, but not in terms of heat and battery. What fanless laptop do you suggest with similar specs to a MacBook Air M1?

The best think I have found that runs Linux reasonably well (still with lots of caveats) is the X13s. And I cannot get a decent price.

Heat and battery is directly tied to the performance per watt.

With equally performing software, the one with the best performance per watt will be run cooler and longer.

The graph I sent is not raw performance, but performance per watt.

Sure, but in practical terms are there any laptop makers that sell any CPU from that list, say a i3-1210U, in a good case and with good cooling?

Because, as I said in the original post, even when Apple was selling Core 2 Duos, their cooling was better than most other manufacturers. I was often buying Macs to run Linux because of this.

Also see what the parent post says about performance per Watt, which mirrors my experience as a user. No current x86_64 machine is close to ARM if you want low heat.
