As long as you're within the total capacity of the RD it could work with one of those Wolf Tooth derailleur hanger extensions, called a Roadlink I think. Others make them, but Wolfies and Wheels Mfg I know for sure use a stainless steel bolt, while the other use aluminum. The Wolfie helps to clear the largest cog only, it doesn't add any capacity, that's for the RD. A 13-42 , at 29 teeth, doesn't leave much room for a triple with much spread. 45t is what most mtb RD are ? That leaves 16t spread for the rings. I for one never use certain combos of course so these "formulas" are theoretical, actual use, if you know what you're doing, can go beyond all that. "Know what you're doing" ... meaning .... not running say a 26t small cog and the last 3 cogs, and likewise, not using the big ring in at least the 2 largest cogs, it really depends on the crank chainline and how much you heed or ignore the horrible sound of cross angling of the chain.
A half step triple would work, like a 44/40/28 for example. The numbers are off the top of my head, not a suggestion. Having the half step would help split some of the large jumps in the cassette.
