That should fail at runtime because Controls.Count is off by one. This code works (at least in my simple test code):

int controlsCount = this.Controls.Count - 1;
for (int i = controlsCount; i >= 0; i--)
{
    if ((string)this.Controls[i].Tag == "removable")
    {
        this.Controls.RemoveAt(i);
    }
}
