I am not sure if it is logical to argue that since red dwarfs can live a long time that any particular red dwarf is older than the sun. It is like arguing that since bristlecone pine can live for thousands of years that a particular individual tree you chance across is thousands of years old - it could be a young sapling.
I do agree that the low metallicity supports it being old, but there are young stars with lower metal levels. Really we just don't know at this stage, but it is an exciting discovery.
