No, but a 45 wailmer is basically a wailord.
Wailord is not available in Firered as are all Hoenn pokemon if you want a Wailord you must trade one from Ruby,Sapphire,or Emerald.
You do not need a Wailord to catch a Registeel in Pokemon Emerald. You may need a Wailord or any other water-type Pokemon to surf to the place where you catch Registeel, but other than that, you don't need a Wailord.
