    No.

    If you are running this from a database other than tempdb you get

    No item by the name of ‘#tbl_tmp’ could be found in the current
    database ….

    Which is not surprising as all the data pages etc. are in the tempdb data files so you wouldn’t be able to rename this to suddenly become a permanent table in an other database.

    If you are running this from tempdb you get

    An invalid parameter or option was specified for procedure
    ‘sys.sp_rename’.

    If you do EXEC sp_helptext sp_rename and look at the definition the relevant bit of code disallowing this is 

    --------------------------------------------------------------------------  
 --------------------  PHASE 32:  Temporay Table Isssue -------------------  
 --------------------------------------------------------------------------  
 -- Disallow renaming object to or from a temp name (starts with #)  
 if (@objtype = 'object' AND  
  (substring(@newname,1,1) = N'#' OR  
  substring(object_name(@objid),1,1) = N'#'))  
 begin  
  COMMIT TRANSACTION  
  raiserror(15600,-1,-1, 'sys.sp_rename')  
  return 1  
 end

    Why wouldn’t you just create a permanent table in the first place then do the rename?
