Both those RCBOs are made by Lewden, one before the recent rebranding, one after. No issue to report.
I also will not be reporting on compatible Schneider devices in Square D and Merlin Gerin boards. Or Hager devices in Ashley boards. Or Tenby and Legrand mixes, or MEM and Eaton mixes, or any of the other combinations I have previously had confirmation of compatibility from the current manufacturers.
The biggest issue I have ever seen with mixing brands is the mixing of different patterns of breaker. By patterns I mean the way they sit on the dinrail and how the busbar enters the terminal. Some have always been of the opinion that close enough is good enough and a little tweak will see the busbar pull in. I have always sought to use the proper gear for the existing equipment, or else not done the job.
