Only Shopify Plus merchants can customize the checkout screen. The alternative would be to create a small app that would "pre-verify" the discount before the checkout (or use an existing app that does so).
Gabe here from Shopify. Discount codes are a great way to increase your conversions as well as offer a great user experience.
So you are offering the "Buy 2 and get X% off" discount and customers are using it on just 1 product instead of 2, is that correct?
With the "Buy X Get Y" discount, and in your example, it's important to remember that the customer must add the following for the code to work:
You could give the discount code a meaningful title like "Buy 3 products and get 10% off on the 3rd product" or similar. That could reduce an incorrect redeeming of the code in the checkout. Are you displaying the code on your homepage like in a header banner or similar? Or are you using the automatic discount feature?
Then, as you mentioned, you can change the error message text - "Cart does not meet discount requirements notice" - in the theme language settings to something more meaningful.

All the best! Gabe
