I extremely doubt it, Punjab and Sind were never known as "Hindustan". Hindustan was the area around Delhi and UP only. Different parts of Punjab in earlier times had different "indigenous names" such as the central Punjab was called "Madra" and at some other points it was called "Taka" etc. Sindh was always called Sindh, even parts of southern Punjab, eastern balochistan and southern KPK were also at times considered "greater Sindh". Kashmir was always called "Kashmir" or "Kasperia" etc. in the past, northern parts of KPK areas along with some adjoining areas in eastern Afghanistan were called "Gandhara" for most part of their history. The northern parts of Punjab were called "Pothohar".
There was no such term as "Hindustan" in use in the ancient past, because the term "Hindustan" originated rather recently only during Turkic and Mughals times for areas around Delhi/UP where their centre of power lied. The word "Punjab" was also coined by the same Mughals to "differentiate" the areas lying west of "Hindustan" that is Delhi/UP areas. I read somewhere that one of the Sikh gurus had referred to himself as "Madari" in reference to the ancient name of central Punjab that is "Madra", the the name "Madra" was in use as late as few centuries ago in some circle of central Punjab. I wouldn't be surprised if the word "Majha" for the central Punjab that is still used in indian Punjab is a corrupted form of the ancient name of this region "Madra" and the language spoken in this area which they call in indian punjab as "Majhi" being originally "Madari" language or the modern standard punjabi of central Punjab.
