Can I prune a leggy plant?

Yes, you can trim back the stems to encourage side branching. Do this in early summer for the best results.

Is it normal for it to be tall?

Green antelopehorn is naturally a shorter, sturdier milkweed, so extreme height with thin stems is definitely a sign of low light.

Green antelopehorn: leggy growth, causes and fixes

Check these first

Evaluate how many hours of direct sun the plant receives.
Check if the plant is being shaded by nearby shrubs or trees.
Review your recent fertilizing schedule.

Likely causes

Insufficient light
Most likely
How to tell: The stems are long and thin with large gaps between the leaves. The plant is leaning heavily toward the nearest light source.
What to do: Move the plant to a spot that gets at least 6 to 8 hours of direct sun daily. If you cannot provide more light, you may need to prune the stems back to encourage bushier growth.
Excessive fertilizer
Possible
How to tell: The plant grows very fast but the stems are weak and cannot support their own weight. This happens if you use too much nitrogen.
What to do: Stop fertilizing for the rest of the season. Green antelopehorn prefers lean soil and does not need much extra food.
