No.
Boneswords state: "No armour saves may be taken against wounds inflicted in close combat
by a Tyranid with a bonesword"
Acid Blood States: "[...] must pass an initiative test or
suffer a wound."
Acid Blood does NOT state that the tyranid inflicted the extra wounds, only that the models suffer an extra wound, which is not caused by the tyranid itself.
