Yes it can.

You could try Barium precipitation followed by Q ion chromatography,
take the FX fractions and activate with Russels Viper Venom. You
could then rechromatograph to separate FXa from the other proteins
(You get a shift in elution profile on activation). It won't be pure
but will probably work OK (Though of course no guarantees are given)
