Should Sony and Valve sue Microsoft in Europe, over their Xbox App in Windows 10?

The EU commission could force Microsoft to remove the app but that is not done overnight.

If they were to do so following a law suit from Valve, would Valve not then be required to remove the Steam app from SteamOS as well though?

I don't know the specifics, but MS was fined €497 million ($794 million or £381 million) in the Media Player case "for abuse of its dominant position in the market". Valve and steam OS are not dominating.
