Short answer: No SAM/AAM can shoot down other SAM/AAM at this moment, only lasers can do this in game.
Long answer: Why would you want to do this?
SAM/AAMs are high velocity and maneuverable targets, you do need something very good and expensive to engage it in order to have a decent chance intercepting it.
Standard procedure of Ruz SAM are using two missiles to engage a aircraft. Imagine how many missiles would be needed to intercept something flying in M3+ and doing 10G+ acrobat.
And imagine how your OPFOR could burn through your magazine and pocket with a *&%$# load of much cheaper SA-2s and 3s. They are old, but if you do nothing those flying telephone poles still have a chance inflicting serious damage.
