Coyotes certainly can respond to better habitat (more prey and less pressure) by producing more pups. Many species respond to improved habitat by having a higher recruitment rate. However, to blanketly say that fawn recruitment can’t be increased by reducing the number of predators isn’t true. There are many published and unpublished examples where the reduction of coyotes has resulted in significant increases in fawn survival. You may search for and read Benson et al. that was published 30+ years ago in Texas based on research at the Weller Wildlife Research area. More recently check out VanGilder et al (2009). They reported 100+% increase in fawn recruitment due to removing coyotes.
Just as importantly researchers from the University of Georgia recently reported that deer are extremely stressed by coyote activity even if when deer aren’t harmed by the coyotes. No doubt deer populations can benefit from removing coyotes.
