You can delete files in recent uploads view in Office Lens, but it does not mean you can delete the file in OneDrive. Is your suggestion the ability to delete files in OneDrive from Office Lens??

Open Office Lens. Click on the 3 ... on top right corner. Click My Files. See the tiny 3 dots next to the date of the file? tap on it and you will see Delete option. Simple.
