You might get away with it but meeting the RO in order to renew your PR card doesn't mean you are off the hook for the next 5 years. The rules say once you have been a PR for 5 years, you must meet the RO in any rolling 5 year period of the previous 5 years counting from any date.
For example, an IO can report you any time you enter Canada if they believe you don't meet the RO. If they do, they will look at the previous 5 years counting backwards from your report date, regardless of how new or old your PR card is.
Similar, if you are outside Canada with your PR card and it is stolen, lost or destroyed and you are in the position of having to apply for a travel document in order to return, they will look at the 5 years previous to your application. They will not ask or care how long your PR card was still valid.
