You have to name the method void OnTriggerEnter with a capital O. Not void onTriggerEnter. Capitalization matters. If you don't name message handler methods exactly as written in the documentation, then the engine won't call them.

There are also a couple other problems in your code:

1. Using GameObject.Find to create object relations is bad. It is slow. It doesn't work when you type the name of the object wrong. It breaks when you change the name of the object. It breaks when you make another object with the same name. It is better to make it a public Text noBox; variable and then assign the correct object in the inspector.
2. The code will throw an error when the player enters the trigger a second time, because noBox will already be destroyed. I recommend to check beforehand if the box still exists:

    void OnTriggerEnter(Collider other)
    {
        if (noBox != null && other.gameObject.CompareTag("Player"))
        {
            Destroy(noBox);
        }
    }
