What you're looking for is a delegate. A delegate is essentially a method pointer which can be invoked later on. 

    private void Form1_Load(object sender, EventArgs e)
    {
        Load();
        //this line 
        InitTimer(() => this.Form1_Load(sender,e));
    }

    public void InitTimer(Action target) 
    {
        System.Windows.Forms.Timer timer1;
        timer1 = new System.Windows.Forms.Timer();
        timer1.Tick += (sender, e) => target();
        timer1.Interval = 5000; // in miliseconds
        timer1.Start();
    }

#region Form1_Load()
private void Form1_Load(object sender, EventArgs e)
{
    Load();
    //this line 
    InitTimer(OtherLoad);
}
#endregion

#region Timer()

private void OtherLoad(object sender, EventArgs e)
{...}

public void InitTimer(EventHandler _method)
{
    System.Windows.Forms.Timer timer1;
    timer1 = new System.Windows.Forms.Timer();
    timer1.Tick += _method;
    timer1.Interval = 5000; // in miliseconds
    timer1.Start();
}
#endregion

IMPORTANT: make your timer call a different method (I used "OtherLoad") in order to avoid setting up the timer over and over again!
