The BBC article says the sub usually dives with a 4 day supply of oxygen.

BBC article must have been edited since my original post. I have edited my post to reflect the new info.

The issue is less the oxygen and more the carbon dioxide removal. assuming the sun has good scrubbers to clean out the co2 then okay, however it can depend how they are powered. There are comparisons to the Apollo 13 situation here.
