Is Alkanol an official part of chemical Nomenclature? There are several references to alkanols here and here but neither of these sources are too reliable. The IUPAC gold book seems not to recognise the term and a quick google search reveals no really good sources.Whilst still not a super reliable source the fact there are no results on Wikipedia but simply a redirect to alcohol also furthers concerns and so the question is: Is the term Alkanol a 'real', 'proper', and 'official' term in chemistry?
IUPAC gold book doesn't recognize it, that's a pretty solid answer. I've never heard anyone say 'alkanol' before either, I've only heard people refer to these as simply alcohols. However, there are people who still use the word 'ethylene' to describe the compound 'ethene' so it could just happen to be some common language I haven't been exposed to.

To be clear, no it's not official, but yes it might be real terminology used by some organic chemists.
