Yes, it should run on Mojave. Typically each LrC version will be able to run on the then current and the two preceeding MacOS versions, i.e.:
Current version 12 will run on Ventura, Monterey, Big Sur.
Version 11 would run on Monterey, Big Sur, Catalina.
Version 10 should therefore run on Big Sur, Catalina, Mojave.
