If they are DRM-free books, then yes. A few publishers and most of the indie authors seem to sell DRM-free over @ B&N. I know that those Samhain Publishing romance freebies that get offered every month are always DRM-free for each one that I've tried dragging onto Lucidor to see if it would open, and I suspect their entire catalogue is, too.
However, B&N don't handily mark all their DRM-free books even with a code phrase such as Amazon's "Simultaneous Device Usage: Unlimited" on the product page, so it's a matter of knowing which publishers are DRM-free or trial and error/asking others.
But I think that publishers which offer DRM-free @ other stores will also be DRM-free @ B&N, such as O'Reilly for computer books and Ellora's Cave & Carina Press for romance and e-Reads for mainstream/genre backlist (they sell MultiFormat over at Fictionwise and DRM-free for Kindle) and likely Subterranean Press and Phoenix Pick for sf/fantasy.
Now that the Kobo Touch has DRM-free Mobi support, I hope the Kobo people will be taking advantage of the new version of ADE which is supposed to allow the use of B&N-DRM style books if the developer decides to enable that option. It would greatly expand the Kobo's versatility and possibly give it a slight marketing edge in the bargain.
