I don't think so. The tramp doc says:

,----
| `scpc' -- `ssh' and `scp'
|      Newer versions of `ssh' (for example OpenSSH 4) offer an option
|      `ControlMaster'.  This allows `scp' to reuse an existing `ssh'
|      channel, which increases performance.
| 
|      Before you use this method, you should check whether your `ssh'
|      implementation supports this option.  Try from the command line
| 
|           ssh localhost -o ControlMaster=yes /bin/true
| 
|      If that command succeeds silently, then you can use `scpc'; but if
|      it fails like
| 
|           command-line: line 0: Bad configuration option: ControlMaster
| 
|      then you cannot use it.  Note, that the option `ControlPersist',
|      if it is supported by your `ssh' version, must be set to `no'.
| 
|      This method supports the `-p' argument.
`----

But probably the best thing to do is to leave org out of it and try opening
the file directly: it seems to be a tramp problem.
