I want to buy a PCIe x4 Wi-Fi/Bluetooth card, but the the Mobo only has x1 slots remaining. Can I insert a PCIe x4 card into a PCIe x1 slot?

Yes, it will work from a PCIe perspective. Having said that, there must be physical room to plug it in. If the MB vendor didn't allow for a physical connection, don't force it. If the x4 card will easily slide into the x1 slot, it should work. Note that you will only have one PCI lane of bandwidth, so you may see a performance drop, but for a wifi card, I'd be surprised if you did.
