Snubberless is new to me. I doubt it existed when the charger was made. I did find this: https://www.st.com/internet/analog/subclass/124.jsp and this https://www.edaboard.com/thread256415.html and I did notice that the snubberless is a 3 quadrant device.
Snubbless means it doesn't typically require an external snubber.
Two in parallel, probably not. It would require double the gate trigger current or two triggers AND more importantly they would not share current equally. You would have to add a low value series resistor to each triac and i would create two opto trigger circuits. Not a good idea to parallel them.
