Is there any way to retrieve via SuiteScript if an accounting period has been locked for a specific subsidiary?

well, my idea here is you can log it via suitescript. But determining it I don't think so

Have you tried doing a taskitemstatus-search?

var taskitemstatusSearchObj = search.create({
   type: "taskitemstatus",
   filters:
   [
      ["subsidiary","anyof","1"], 
      "AND", 
      ["period","abs","152"], 
      "AND", 
      ["itemtype","anyof","PCP_LOCK_ALL"]
   ],
   columns:
   [
      search.createColumn({
         name: "period",
         sort: search.Sort.ASC
      }),
      "subsidiary",
      "itemtype",
      "complete",
      "inprogress",
      "lastmodifieddate",
      "modifier"
   ]
});
