Yes and No.
Yes you can use RMAN to Disk and then use any utility (NetBackup without 
the Oracle module, or TAR or CPIO)
to copy that backup to tape.
No, you cannot make RMAN "aware" of the tape backups. Thus, RMAN cannot 
restore directly from tape as it
does not know which tape has which backup set.  You will have to use your 
NetBackup catalog or a manual / scripted
catalog (if you use, eg. TAR or CPIO)  to restore the files from tape to 
disk (the backup destination location
or any other directory)  and, _then_  use RMAN to restore from that disk 
location to the database datafiles location.
