Yes, I'd say anything you can get with noob gains is fair game. By noob gains I mean everything you can get from just increasing the weight a bit every time you hit the gym.
Once you need more complicated programming to make progress, your noob phase is probably over.
For what it's worth, I got up to 170kg backsquats at about 72kg body weight back in the day. The most complicated programming I did was a weekly cycle. ('Texas method'.)
But that was only down to thighs parallel to the ground. Years later I worked more on my flexibility to be able to squat all the way down (but with less weight).
