No.  Booting in rescue mode will cause the system to try to find
existing Linux partitions on your hard drive and mount them as
/mnt/sysimage ("/" will be mounted at "/mnt/sysimage", "/usr" will be
mounted at "/mnt/sysimage/usr", etc.)

Tape drives are sequential storage devices, NOT block-oriented random-
access storage devices.  Only block storage devices (such as disks) can
be mounted.  You can install a minimal system and recover from tape,
but you can't mount it.
