Yes, depending upon the actual level. Iron is a heavy metal, and all heavy metals can kill life, be it bacteria, plant, animal, fish. However, iron is also an essential mineral to all life. So it is the level of iron that matters, and I've no idea what that might be. Public water systems obviuosly test for iron and other heavy metals, and take steps to ensure the levels are safe for humans. Is your neighbour treating his water, or perhaps not drinking it? What is safe for humans may not be safe for fish living in it.
Water conditioners that detoxify heavy metals (and most, but not all, do) will usually only be effective with trace levels of the metals, such as might be found in municipal water. This takes water safe for humans but not for fish, and detoxifies the metals so it is safe for fish. Live plants also take up these metals, but this is obviusly limited too.
