No.. plants don't waste energy.. they use whatever they can get. Cutting the leaf off may open up a lower section for more light, yes.. but it will stress the plant to cut parts of it off..
If you do decide to prune fan leaves off.. do one at a time.. every few days.. never cut more than 2 fan leaves off in a day.. as it really is unnecessary.

What do you think the plant uses to catch that energy from the light??

The Fan leaves..


Try tucking.. and tying.. you can manipulate the growth of the plant just as well and not worry about cutting parts of it off before it's time to.

Hope this helps,
