Just a suggestion: would something like "check whether
paper-button[is=action-link] is needed here", convey the intent?

             <paper-button is="action-link" on-tap="onConfigurePin_">
               [[getSetupPinText_(hasPin)]]
             </paper-button>
           </div>
         </paper-radio-group>
       </div>
 
-      <div class="settings-box single-column">
-        <settings-checkbox pref="{{prefs.settings.enable_screen_lock}}"
-                           label="$i18n{enableScreenlock}">
