Lots of webmasters have a website at their own domain and a blog somewhere else. And link between the two in the same way that they would have done, if their blog had actually been on a subdomain of their main website. It is possible that this may create problems with some search engines, but, personally, I have never heard of an actual case where it was.
Just take care that your links are natural and organic and genuinely helpful for your visitors.
