steam
A friend of mine said he's seen me playing a game (Batman: Arkham Origins) on Steam while I was at work. Since he only has two friends in his list I tend to believe him (ruling out a mix-up)
But the game does not show up on my recently played list. Is there a way to play a game without appearing in that list or to delete an entry?
Just to be sure, I changed my Steam password.
This sounds like the file storing that information got corrupted.
%AppData%\Microsoft\Windows\Recent\CustomDestinations493e32cec2810e2e.customDestinations-ms, but you might have a different one.Since a recent update, you can now set it so that only your friends, or no-one can see what you're playing.
Go to the Steam community settings page here, it can be found at that link or as this answer states, on Steam go to Profile > Edit Profile > My Privacy Settings > Game details
At Game Details you can choose between public, friends only or private.
This category includes the list of all games on your Steam account, games you’ve wishlisted, your achievements and your playtime. This setting also controls whether you’re seen as "in-game" and the title of the game you are playing.

No its not possible to delete or remove those entrys since they are all stored server side i assume. If you search you find people on reddit having similar issues, which can be traced back to a buggy steam beta version and free weekends showing wrong information on the beta client.

Maybe those bugs and your friend seeing you in a game you didnt even play at the time are related
