Well the most compelling statement for it comes from a research paper titled
VISUAL EFFECTS OF HELICOPTER MANOEUVRE ON WEAPON AIMING PERFORMANCE by P.R.Michael. T.E.Jardine and M.K.Goom in their role at British Aerospace Dynamics Group
BAe Dynamics had incorporated BAC (Guided Weapons) the developer of Swingfire, in 1977. Mr. Jardine being the Chief Systems Engineer for Anti-Tank Guided Weapons at BAe Dynamics.
This dates the paper as being written after hawkswing was cancelled, but the paper states that the research detailed was carried out as part of the development of a helicopter-launched variant of Swingfire, later clarifying that such a weapon became designated as “Hawkswing”.
And in outlining the characteristics of Hawkswing, states that the project intended to arm both Lynx and Gazelle with the missile system.
So basically we have a primary source of info from the weapon system manufacturer, saying they started development of Hawkswing for the UK and it included arming Gazelle.
The full paper can be read online here https://apps.dtic.mil/sti/tr/pdf/ADA065234.pdf published by NATO as part of a 1978 scientific journal. It’s the 25th article in the journal, and starts on page 213 of the digitised version.
And so far as Gazelle’s anti-tank role for the UK goes, there’s a source in Westland’s briefing notes for Pathé News’ coverage at the 1972 Farnborough air show (then known as the Society of British Aerospace Companies Show)

However, “Hawkswing AT missile” is only given by name as part of the briefing notes for the Lynx display
Also, if anyone’s having another trip to the Kew one of these days:
