Yes, but such a load out would leave little room for self-defense munitions for the fighter. Nor would just 2 missile per fighter translate into a meaningful strike.
IMO, a J-15 must at least carry 3 YJ-83 along side self-defense missiles. Such a loadout is impossible on the current carriers.
For two tons maximum payload, two YJ-83 assuming 715kg (weight of the sea launched YJ-83) would mean over 1400kg, which gives you over 500kg for AA missiles. PL-8 weighs only 115kg. That's more than enough for two PL-8s.
You could also alternatively use three YJ-91 (600kg) or four C-705 (320kg).
This is more than enough for a "small" foe. Otherwise you are better off launching antiship missiles en masse in salvoes from surface ships like the Type 052D and 055. These ships can launch far more devastating YJ-18 or maybe YJ-12 missiles.
