No. But you can include a document into a document with different document
class, as LyX strips the preamble of included documents. You will get a
warning, as there might be incompatibilities.
You can combine this with branches, creating the same branches in both
documents but activating just one ("global" vs "standalone", say) in
Document>Settings.
