You can use personal JS in Special:MyPage/wikia.js. You wouldn't move the Discussions link per se, but hide the current one and add one to an existing menu.

It would help to know:
 * 1) A link to the wiki where you want to do this.
 * 2) Which menu you want to put the Discussions link in.
 * 3) What position in the menu you want the Discussions link to be at.
