Sure, but be warned, it's complicated... :)

myCheck.Checked = (IsInterested.equals("yes")) ? true : false;

Then, on the CheckChanged Event:
IsInterested = (myCheck.Checked) ? "yes" : "no";

I'm assuming you want to do this in a data grid?  Is the underlying data
source a DataTable?  If it is then I would create a column on the DataTable
which has an Expression property set to:

iif(%column%, 'Y', 'N')

   Then, bind to that column.

   You could also create a new DataGridViewTextBoxColumn which writes the
appropriate text, but that seems like way too much work.

Here is a derived class that includes properties for setting valid yes/no
values and setting/getting the checked text.

   public class CheckboxEx: CheckBox
   {
       private string _YesValue = "Y";
       private string _NoValue = "N";

       public string YesValue
       {
           get { return _YesValue; }
           set
           {
               _YesValue = value;
           }
       }

       public string NoValue
       {
           get { return _NoValue; }
           set
           {
               _NoValue = value;
           }
       }

       public string CheckedText
       {
           get
           {
               return this.Checked ? _YesValue: _NoValue ;
           }
           set
           {
               this.Checked = string.Compare(value,_YesValue,true)==0;
           }
       }

   }
