На буржуйском форуме не нашел прямого подтверждения, что так делать можно, но вот что написано в прибитой теме с гайдами по капу халки:
Раскрывающийся текстIt is perfectly doable to have in your list 4 Hafza and up to 6 other, linkable troops - say, Djanbazan HMG (for anti-Camo work), Sekban HRL (for fiery template rain), Druze LGL (for Speculative Fire), Azra'il Feuerbach (for anti-TAG / anti-HI work), Kaplan Spitfire (for quick offensive operations) and Ghulam Doctor (just because), then switch who's in your Link Team every turn depending on the situation. This has, of couerse, its limitations, but on the other hand gives a very elastic Link Team combo - a tool for every job plus link bonuses.
Короче можно.
