Tachycardia means rapid heartbeat. We know that normal heartbeat is when your pulse is between 60 and 100 and any rate above 100 is considered tachycardia. So atrial fibrillation falls under tachycardia because it can lead to fast heartbeats, but atrial fibrillation is not the only tachycardia diagnosis. There are many other abnormal heart rhythms that fall under the guise of tachycardia.
