It is, but using a PHP E_ERROR halts the script and doesn't allow for a friendly message, just a white screen.
Include() only issues an E_WARNING, allowing a message and rest of page, or as my example with an exit.

Ideally you would include the header/content/footer/navigation etc with a message then exit() if desired, or "other" criteria if the file was not available.

Something like this:

<?php
$file = "wp-content/plugins/stuff.inc"
if (file_exists($file)) {
  include($file);
}
?>
