No, not really. There is an experimental wordpress hive provider for umbraco v5.x, that theoretically would allow umbraco to read/write wordpress data, but its not really something you can just start using - it was more a proof-of-concept demo.
Wordpress is more of a competitor to Umbraco, as opposed to a tool that you would (normally), use in conjunction.
If you are interested, here is the sourcecode of that wordpress provider for umbraco: https://bitbucket.org/boxbinary/hive-wordpress-provider
and here is a blog that discusses it: http://labs.thesedays.com/blog/2011/11/25/a-blob-storage-hive-provider-for-umbraco-5-beta/
