I have been proposing and leading the projects such as Project A and Project B in the company.
Is "have been proposing and leading" grammatical? Assume I have already proposed, and I am currently leading.

I find that the projects such as is inherently ungrammatical, because the use of the means that the projects in question have already been mentioned.
I would say that omitting the is correct:
I have been proposing and leading projects such as Project A and Project B in the company.
As for whether have been proposing and leading is grammatical or not, it looks fine to me. I suspect that your question arises from having one modal verb and two participles. If so, that's perfectly ok, and very common. Consider this:
They have been laughing and talking together for three hours now.
You don't need to say
They have been laughing and have been talking together for three hours now.
