Shortening boolean with if statement for document version comparison

Can this be shortened to one line?

bool areVersionsEqual = documentComparer.Equals(version, imported);

if (areVersionsEqual == false)
  {
    changedDocument.Add(imported); 
   }

Sure. Use the Not operator.

if (!documentComparer.Equals(version, imported))
{
    changedDocument.Add(imported); 
}

To explain a little, it's bad practice to do things like this.

bool boolean = true;
if (boolean == false)
{
//...

because it's completely equivalent to saying

if (true == false)

and can be simplified down to

if (false)
