If you wire them incorrectly or they're not charged properly then it is possible for them to catch fire. Most of these batteries have a IC in them which monitors the battery and records stats so it might not work anyway. You can buy fairly cheap Dell batteries on eBay. Don't know what the quality is like or even if they're real Dell batteries.

That's probably a really bad idea with Lithium Ion cells. It's almost guaranteed to drop their voltage below the critical level where they can't be safely charged again.
