I don't think so. Books Online says in the Remarks section for DBCC 
OPENTRAN:

   Use DBCC OPENTRAN to determine whether an open transaction exists within 
   the transaction log.

You have a transaction that this far has only read data, but has not 
performed any updates. Therefore it is not preventing the log from being 
truncated.

Only if you have a trace running which captures the statement.
