The AMD website says the non-PRO 7x40 laptop Ryzens have no ECC support[1], and the Framework folks have said that AMD told them there’s no ECC on non-PRO 7x40 laptop Ryzens[2]. If plugged in, ECC modules will work, but without the error-correction functions. (Edited to reflect the current state of the website, as it used to say ECC support was present[3].)

(here “FP7r2” is the version for use with interchangeable DDR5 modules rather than with soldered LPDDR5)

This is very weird. I have saved the page from your link on the 17th of July. In the saved page it is written: "ECC Support: Yes (FP7r2 only; Requires platform support)" The same was written at all AMD Rembrandt and Phoenix models, and it has been written in all such mobile CPU specifications at least since the beginning of 2022, so at least during a year and a half, if not more. The ECC support was available only with DDR5 SODIMM memory, not with LPDDR5 memory, and only in the FP7r2 package, and neither in the FP7 nor in the FP8 packages. Perhaps AMD has discontinued the FP7r2 package, but this is not mentioned in the specifications. Either that, or they have decided right now that they may charge more for PRO models, or save on testing on non-PRO models. Either way, it seems a stupid move for AMD to degrade right now their mobile CPU specifications, when Intel will launch Meteor Lake, which is likely to be better than AMD Phoenix. AMD mobile Zen 5 will be better than Meteor Lake, but until its launch it remains about a half of year, supposing that it will not be delayed.
