How would I make the GetComponent field a variable?

What I'm trying to do is this,

 using UnityEngine;
 using System.Collections;
 
 public class CheckBool : MonoBehaviour {
     
     public string scriptName;
     public string varName;
     
     
     public bool Check () {
         Component other;
         
         other = gameObject.GetComponent(scriptName) as Component;
 
                 //This is the issue here. I want to get the variable on other using the name 
                 //stored in the varName variable.
         if (other.varName == true) {
             Debug.Log ("Welp, it was true");
             return true;
         }
         
         Debug.Log ("Sorry, it was false");
         return false;    
     }
 }

I want to access varName on other. But varName is a variable on the script. How would I do this?

Thanks.
