If you're doing it in a preprocess, I'd suggest to base your code on LinkSeparateFormatter.php. It shows the idea on how to get the title from the link field. Here's a way to do it.

use Drupal\Component\Utility\Unicode;

//...

$field_link = $entity->field_link->first();
$link_url = $field_link->getUrl();
$link_data = $field_link->toArray();
// If you want to truncate the url
$link_title = Unicode::truncate($link_url->toString(), 40, FALSE, TRUE);
if(!empty($link_data['title'])){
  // You could truncate here as well
  $link_title = $link_data['title'];
}
$variables['content'] = [
  '#type' => 'link',
  '#url' => $link_url,
  '#title' => $link_title,
];
