The answer is "Yes", but a little bit of preparation may be required first. Where a deck has been previously coated with a conventional oil, such as Cabot's Natural Decking Oil, you must first check that the surface has lost its water repellency.
All that's required is a simple water spray test. Droplets of water are sprayed or sprinkles onto the surface. If the water "beads" on the surface, it is still water repellent and further weathering or sanding is required. If the water soaks into the surface, the repellency has gone and you can prepare to apply Cabot's Aquadeck. Simply clean the surface with Cabot's Deck Clean to remove the dirt and extractives an then apply Aquadeck following the instructions and spreading rate as detailed on the can.
