Yes, Intel called their 8048/8748 and its scions microcomputers because they contained everything necessary to provide the function of a complete computer on a single chip. The 8022 was in a 20-pin DIL package, IIRC. The term microcontroller was not yet popular though it was becoming so by the time (1982 or so) the 805x's were becoming more common.

The term "controller" was used quite profusely in the Signetics description of their 8X300 IIL (integrated injection logic) controller commonly seen in tape and disk drive controllers. It was called 8X300 because the original version had only 8 instructions, albeit quite complex ones, each of which took 300 ns. Of course, the 8X300 required external memory and I/O so it was never considered a microcontroller. Later versions required only 250 ns, but the 8X300 name stuck. Because EPROMS were too slow, they used bipolar PROMs.
