Is it possible to call a method which has optional arguments with Invoke?

void Start()
{
this.GenerateLevel(true);
}

    private void GenerateLevel(bool isFirst = false)
    {
        if (isFirst || this.IsTimeToGenerate())
        {
            this.currentLevel = Instantiate(Levels[Random.Range(0, this.Levels.Length)], this.GetNewPosition(isFirst), Quaternion.identity) as GameObject;
            this.currentLevel.transform.parent = this.transform;
            this.previousLevel = this.currentLevel;
        }

        Invoke("GenerateLevel", 0.5f);
    }

Is this code executable?

No, you cannot use Invoke with methods that have parameters (optional or required), but you can still use coroutine that is more elegant in your case:

	void Start ()
	{
		StartCoroutine(GenerateLevel(true));
	}
	
	IEnumerator GenerateLevel(bool isFirst = false)
	{
		while (true)
		{
			if (isFirst || this.IsTimeToGenerate())
			{
				this.currentLevel = Instantiate(Levels[Random.Range(0, this.Levels.Length)], this.GetNewPosition(isFirst), Quaternion.identity) as GameObject;
				this.currentLevel.transform.parent = this.transform;
				this.previousLevel = this.currentLevel;
			}
			yield return new WaitForSeconds(0.5f);
		}
