Probably. W&H didn't see Spike as any sort of threat, and didn't want him as any sort of ally. That's if they saw him at all, or were even aware of his existence.
Would Spike have been likely to go to W&H to get his chip removed?. Maybe, if he knew anything about them, but I can't recall him having any dealings with them, or had even so much as heard of them. Maybe he just didn't even know that they existed, or, if he did, had no scope of their actual power. Or maybe, by the time that the idea did occur to him, he was so fixated on Buffy that having his chip removed was no longer any sort of priority to him.
