About passing a parameter in an object when I start the thread, I can't do this because in the Compact Framework (not the full .NET) only the method Thread.Start() is supported, the method Thread.Start(Object) is not supported.

Aw, darn. Without that, it's not possible to pass the form as an argument.

Since AggiornaLabel is a method of the form (as should be), you'd need to have a reference to the form in order to invoke it. An ugly bypass would be to use a "shared" member, aka a static method. Works similar to the shared integer called 'iii'.
Imports System.Threading

Public Class Form1
    Dim MyNewThread As Thread

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click        
        'create the thread 
        MyNewThread = New Thread(AddressOf MyThread.MyThreadExecute)
        MyNewThread.Name = "NuovoThread"
        MyThread.ThatForm = Me
        'start the thread
        MyNewThread.Start()
    End Sub

    Public Sub AggiornaLabel(ByVal What As String)
        If InvokeRequired Then
            Invoke(New Action(Of String)(AddressOf AggiornaLabel), New Object() {What})
            Return
        End If

        Label1.Text = What
    End Sub
End Class

Public Class MyThread
    Private Shared miii As Int32 = 0
    Public Shared ThatForm As Form1

    Public Shared Property iii() As Int32
        Get
            Return miii
        End Get
        Set(ByVal value As Int32)
            miii = value
        End Set
    End Property

    Public Shared Sub MyThreadExecute()
        Do
            iii = iii + 1
            ThatForm.AggiornaLabel(iii.ToString)
            Thread.Sleep(100)
        Loop
    End Sub
End Class
That's abusing things a bit; a class that's never instantiated would be a module, eliminating the need to declare each member being 'shared';
Module MyThread
    Private miii As Int32 = 0
    Public ThatForm As Form1

    Public Property iii() As Int32
        Get
            Return miii
        End Get
        Set(ByVal value As Int32)
            miii = value
        End Set
    End Property

    Public Sub MyThreadExecute()
        Do
            iii = iii + 1
            ThatForm.AggiornaLabel(iii.ToString)
            Thread.Sleep(100)
        Loop
    End Sub
End Module
