Hello bwv998! Yes, you can remove those dried up leaves. It is normal for the older, lower leaves to dry up.
You can also cut off the top section, allow to callus, and repot cut off part in a gritty media. Position in some shade then move to more sun outdoors, it likes lots of light and warmth. It is growing etiolated like that, getting too leggy, since it is seeking more light. Sometimes, it is just not the best to have them indoors, they really like outdoor growing, then just have to move them back indoors when the seasons go cold again.
