I think so.
A few years ago, I saw people posting up where they have seen lions in person or on game cam. 254 counties in Texas, and less that 20 did not have a report of a sighting, as best I can remember. I've killed hogs from +400 pounds down to the size of a football, and some as close as 20 yards. My belief is, if a predator has enough to eat, the predator will flourish. There are hundreds of thousands of hogs all across Texas. And I've seen them making a living in some damn hard country, where you would not expect to fin them. My bet is the lion eats as often as he likes. And it is a steady diet of feral hog.
Deer are way easier spooked than hogs. and have better eye sight. If a lion comes in from down wind, he has got the advantage on a sounder. I smoke every coyote I see, but I've got a bit of love for the Bobcat and Mountain Lion.
