I figured it out, I'll psot the code soon.
I'm adding comment atm.

Code:
'show tab
        Dim txt As Object
        Dim tabp As TabPage
        'loop through all tabs in
        For Each tabp In TabControl2.TabPages
            'loop through all objects in the tab
            For Each txt In tabp.Controls
                'check if it's a label
                If TypeOf txt Is Label Then
                    'if it's a label, see what the text is
                    If txt.text = "Autozone" Then
                        'if it's that text, move it to the first tabcontrol
                        'it'll be removed from the second tab
                        TabControl1.TabPages.Add(tabp)
                    End If
                End If
            Next
        Next
Code:
 'hide tab
        Dim txt As Object
        Dim tabp As TabPage
        'loop through first control
        For Each tabp In TabControl1.TabPages
            For Each txt In tabp.Controls
                If TypeOf txt Is Label Then
                    If txt.text = "Autozone" Then
                        'add to second
                        TabControl2.TabPages.Add(tabp)
                    End If
                End If
            Next
        Next
This code works fine
