Yes you definitely would be able to keep those corals, granted you would have to put them higher up in the tank but you'd be able to keep them.
The difference is efficieny, PC
bulbs were desgined poorly in that they lose a lot of light inside the bulb itself from restrike and they aren't as efficient in putting the energy into light instead of heat, etc.
Reference, I had 48w PC
lighting over my tank, now I have just 36w and I'll be able to keep much higher light corals with no issue where before I wouldn't have even thought of it.
Watts are no matter any more in the aquarium lighting, especially since certain LED
fixtures (certain one I'm referencing being 21w) is comparable in light ouput (intensity, for simplicity's sake) to a 150w MH
in a certain tank/area
