Sure.  You can use something like the UNIX command "tee" in "archive_command"
to create a second copy of the WAL archive.

You could also use the same archived WALs for both purposes and
from several machines by putting them on a network file system.

You will have to promote the standby, make sure future client
requests will go there (a connection pooler or a virtual IP address
can help here) and build a new standby.
