It would be illegal and would be very risky for Renault to do if McLaren found out. Again, if McLaren found out, why would McLaren go about it so casually letting them have it and moving to Mercedes after a season and a half. Renault may be able to better utilize their engine or have their parts pass through a more rigorous QA process but I doubt they are giving less horse power.
My gut feeling is that Seidl is probably betting that Mercedes will end their F1 participation in the next 5-10 years.
Today there is a major issue if Mercedes pulls out and that is that their current customers are not capable of wins. It's unlikely they will challenge for wins in the near future. This means that Mercedes either needs to stay in F1 as a works team, or they need to accept having their engines in midfield cars. When McLaren gets Mercedes power, if they are able to fight for wins and podiums, this makes it possible for Mercedes to pull out as chassis manufacturer and still have their engines fight for wins.
Toto Wolff said that they wanted to have a more competitive customer team. This kind of statement is in allignment with Mercedes having more options for pullout if McLaren does OK. Seidl is probably well informed and can guess what the board of Mercedes might want to do down the line.
In the end, having Mercedes power will give McLaren a clear benchmark and remove any kind of potential excuses. Hopefully it will mean an power increase and reliability improvement, all of which will help them catch up to top 3.
If there are 10 engines on the pre issue test bed, they can vary by several KW and be slightly finer balanced etc but be identical engines.
By picking the best 4 engines, best 4 electrical sets etc the end result can easily be that the factory team is substantially better than that issued to a customer even though they are 'identical in spec and detail'.
All within the rules and above board, but result in being well above the customer.
I don't know how true that is today with manufacturing tollarances being so much smaller. The differences in power will be much smaller as well.
