Yes, you can use the FDK form console for tasks, in the item kind enter "task" and the item id will be the task id (including the $). You can find the task id by hovering over links in the Share client, the id is part of the URL. You won't find the tasks via the node browser as they are stored in JBPM DB tables not Alfresco DB tables i.e. tasks are not Alfresco nodes.
