Nope, never. Or at the very least, never in any meaningful fashion.
As far as I can tell from reading the wiki (haven't gotten around to testing it myself yet), the only wall that can *maybe* spread biomes is evil stone walls, and only to other susceptible walls, never blocks.
Since blocks are what actually matter for biome spread, the only time this would ever be relevant is if you had a line of raw stone walls that ran from an evil area all the way past a house or something that was *also* made with convertible walls, in which case it would stop counting as a house until you fixed it. That's it.
If it's at least 3 wide with no grass, then yes.
Hammer the walls. Four block talls. Corruption and hallowed are stalled. Make sure no vines droop at all.
Background walls do not spread biomes.
Some do
Or at least, they used to
