Theoretically, sure, why not. TBH tho the reasons stated in the OP are kinda weak. Holding hands at someone's request is neglegible and as far as the 'hello sailor' line goes, a lot of 'homoerotic' slang is thrown around where I work. For example where I work, we always pretend to jerk off using giant tools, its not gay, just goofy.
