Technically, no. However, if the tail drags the ground, the horse could step on it and cause pain in the dock/tail area, causing great discomfort for the horse. The horse may buck/kick/rear/etc. The horse should NOT step on it's tail when it lands. If it does, you should trim the tail a 2-3 inches to ensure he doesn't step on it again.
My tip: If the horse cuts, he shouldn't be jumping over obstacles. If you mean leaping to cut the cow off, then his mane/tail shouldn't be so long(long enough to reach the feet). It may look nice, but it just isn't practical, sorry to disappoint. I personally do hunter-jumper/pleasure English.
Well you can cut the mane and tail, it just depends on the breed and how you're showing the horse. Cutting the mane will result in a horrible haircut though if not done right. Cutting the tail to trim up the bottom can make the tail look fuller.

Cutting a horse's tail would not typically result in death, but it can cause pain, stress, and potential complications such as infection.

First you'll have to stop the itching. Have your horse checked for worms and possibly dewormed. Then shampoo the tail with a horse shampoo and do not comb/brush it. Hand pick any tangles you find. After it is dry you can braid it and let it go like that or place it in a tail bag to protect it further. Only wash the tail once or twice a month or the hairs will dry out and break.
