Of course you can. Just cut where ever you want more or less. No 45º cuts or nothing like that, just snip at the desired height. the only exception to that is that you leave behind an adequate amount of foliage to be able to generate new growth. You can grow a plant all the way to 6+ feet then top it back down to 6 inches, so long as the leaves that remain on the plant can photosynthesize and help build the new growth. Frow what I saw, you had 2 large fan leaves with a few smaller leaves below that which is more than enough to generate new shoots. However, in your case, because those 2 shoots are already growing, 2 new ones might not arrive and I actually believe she will have to deal with less stress. As a newb, I myself have undertaken to try every known and proven technique at least once. My last grow was a male in soil, with 4 clones and 2 germed bag seed in an aeroponic, with those plants I sampled aero, soil, DWC, FIM, multiple toppings (my favorite BTW is topping), foliar feeding, defoliation and anything else I could imagine to try. Heck, it took about 6 people to talk me down from trying LA's Flux technique on my current grow as I really wanted to try it.
If you are still unsure of where to go with your grow, maybe spend some time on YouTube watching vids about different manipulative growing techniques till you find one that seems right to you. IMO, topping is one of the most basic and works very well for me. With topping, you know you will always get "2" new shoots, and that knowledge will empower you to determine how your plant grows and in LA's case, how many flowering branches will be produced. My first (male) plant, I had topped it 3 times. Once to make the main split, then about 3" after that I topped each of those 2 again, making 4 main shoots. With a razor, or cleaned scissors, cut wherever you want the main stalk to split. This changes growth from true vertical to 2 diagonal growths. It still grows up, but not as fast which give me more time to plan how my plant is not going to grow into my HPS and burn itself. I also use LST to maneuver branch tips (buds) around to get light to otherwise unreachable places.
Us newbs are like children and need to find out who we are inside. The sooner we find our niche, the sooner we can perfect our desired methods. To get to that place in a shorter period of time, we need some trial and error and lack of fear of failing. I don't know your situation, like if you "need" meds and have no other options. A situation like that, it may be imperative that you harvest ASAP. If you have other options and can play around, I'd suggest to do so, or even to get a second completely not important grow going just to experiment and learn. I have 4 clones now that I have zero intention of keeping. They were taken from a flowering plant that had finished it's stretch period. These type of clones are very hard to get to root, and b/c of that, I want to take the Pepsi challenge just to see and of course learn. I will likely gift away the survivors, but if I find no good people to
donate to, I will toss them.

Mine don't look as pretty now.....
