No, Mew cannot be caught or found in Victory Road.
Its impossible to catch Mew in anyway without cheating. The Pokemon you might be thinking of is MewTwo and it can only be caught in Cruelean Cave.
either use action replay or event or catch wild in victory road after you get mew.
no but it would be nice.
