You can search for specific controls that exist in your current form using the Controls.Find method (see docs). This will either return the control(s) that have been found in a Control[] array and in case nothing has been found, it will return and empty Control[] array.

In you case you can check on the array. If it's empty you know there's no controls yet with the name you want to use!

var controlFound = this.Controls.Find(NameYouWantToUseAndCheck, true);

if(controlFound.Length == 0)
{
    // No existing control has been found with this name, you can safely make your new control
}
else
{
    // An existing control has been found with this name, use another name or do whatever you want!
}
