You can change the filename by setting the fileName property, as indicated in the export plugin documentation.

var chart = AmCharts.makeChart("chartdiv", {
  // ...
  "export": {
    "enabled": true,
    "fileName": "your new file name without extension", 
    // ...
  }
});

You can also set the fileName at the format level through the menuReviver callback. You can use this to override the top level fileName property depending on the format.

var chart = AmCharts.makeChart("chartdiv", {
  // ...
  "export": {
    "enabled": true,
    "fileName": "top level filename",
    "menuReviver": function(item, li) {
      if (item.format === "JPG") {
        item.fileName = "customJPGName"; //different file name for JPG files
      }
      return li;
    }
  }
});
