Nope. The only way it would be possible is if you had a JDBC driver that spoke to access. That's issue number one, although a quick google search shows there's a number of them available.
The second issue is the hibernate dialect. Hibernate won't recognize access as a database platform and therefore will not know what dialect to apply. In these cases you can specify the dialect, but I wouldn't know which one to recommend (dialect knows things like special functions, SQL-92 compliance, special syntax requirements, etc.).
Normally I would never suggest going with Access. You can leverage the HSQL database for demo purposes, and you can run with MySQL on windows so there is a better option to get a real database.
No reason to try to get Liferay working on Access, in those cases...
