Sure, I've seen embedded work done with anything from assembly to Lisp. But it's all marginal, trying to get into embedded development without learning C would be very career limiting. For example, not sure how many new projects are started in 2018 with Pascal on PIC but suspect not a lot.
Perhaps the most popular non-C development platform these days is Arduino on Atmel 8 bit chips, but it is still really a dumbed down version of C(++).
