In this case, you can have a fact that uses the code that you posted above. Facts are just Ruby so you can pretty much do whatever you need and return the boolean as the fact content.
However, you may need to get a bit fancy and use a confine to ensure that only that one node is triggering the fact run and not every node in your infrastructure. The most precise way to do this would be to drop a file on the system whose presence indicates that the fact should run and bind the confine to the presence of that file. More information on creating custom facts can be found at https://docs.puppetlabs.com/facter/2.2/custom_facts.html.
