It might. But you really need to have good conditions: soil, temperature, precipitation, altitude, sun/shade, etc.
And you also need to properly prune, fertilize, and pollinate.
There may be places in Texas or California where coffee could grow or even fruit (although I doubt that Texas has any good locations for this), but again, the quality of the bean would likely be very low.
I just read that this kind of coffee plant needs to be at an altitude of at least 1800 feet above sea level. Will it fruit at lower levels?

It might grow. The question is whether or not the coffee would be drinkable. It most likely would not be.
There are some people trying to bring it to California, but I'm not convinced that they will get anything of good quality there either.
