Not without all of the WAL files from the point pg_start_backup()
was run until the point pg_stop_backup() was run.  Earlier WAL
files won't matter.  You will be able to restore to any point in
time from when pg_stop_backup() onward as long as you have an
unbroken series of WAL files (and any .history files which were
generated).
