There isn't an option to delete an account outside of the admin panel. However if the account you made first never got activated then it wont cause a problem. Unactivated accounts are very limited in what they can do (as probably you guessed), so it being attached to your IP wont make a big difference if someone spots it. The rule is there to make sure people don't create more than one account for the purposes of spamming, or to make themselves more popular, voting scams, things like that.
On the other hand, if you'd prefer to use the account you created first, I can activate it for you, and then deactivate this one. It's your choice.
