It's not "recommended to have at least one" per se, it's just that tantou at lower levels outperform wakizashi and uchigatana at higher levels. Your team won't be disadvantaged, but with lvl7x uchigatana and lvl5x wakizashi you might have to prepare to lose some troops, as well as not being able to kill the rarity-5 yari or enemy wakizashi on the first turn. If you swap out Namazuo for another tantou, you'd probably only need to level them until lvl50 before they can start OHKO-ing the stronger enemies? For 6-1 and 6-2 at least.

6-3 and 6-4 have indoor stat boosts/deboosts as well, so I think uchigatana and wakizashi perform better there than in 6-1 and 6-2. You can always try with your current team and return if you feel like you're taking too much damage. From there just change the composition or troops or level them more until it works out.
