Unless you have proof that Bioware and LucasArts released the image into the public domain, no. Since public domain allows people to use an image without paying royalties, I'm fairly confident in my guess that neither Bioware or LucasArts made that choice.

Under the circumstances, if the image is allowed for use at all, it'll be via Fair Use. I can't make that determination for you—see the tutorial for the legal considerations involved—but it's either that, or permission (LucasArts and Bioware aren't going to give that either), or it's nothing.
