Combine the 2 screen sizes and set your form to that resolution. Something like:

int height = 0;
int width = 0;
foreach (screen in System.Windows.Forms.Screen.AllScreens)
{
  //take smallest height
  height = (screen.Bounds.Height <= height) ? screen.Bounds.Height: height;
  width += screen.Bounds.Width;
}

Form1.Size = new System.Drawing.Size(width, height);

To override the maximize button you can check via WndProc for the maximize event

const int WM_SYSCOMMAND= 0x0112;
const int SC_MAXIMIZE= 0xF030;
protected override void WndProc(ref Message m)
{
    if(m.Msg==WM_SYSCOMMAND)
    {
        if((int)m.WParam==SC_MAXIMIZE)
        {
            MessageBox.Show("Maximized!!");
            return;
        }
    }
    base.WndProc (ref m);
}

or register to the Resize event of the form (you should check if it's resize or an maximize) (MSDN)
