I'd say yes, as long as the error is the one defined for 506 
(<http://greenbytes.de/tech/webdav/draft-ietf-webdav-bind-latest.html#status.506.loop.detected>):

"The 506 (Loop Detected) status code indicates that the server 
terminated an operation because it encountered an infinite loop while 
processing a request with "Depth: infinity". This status indicates that 
the entire operation failed."

I think it would be better to return a 409 with 
DAV:error/DAV:cycle-allowed here.
