Not really. The CPU part of a microcontroller, sure. But a microcontroller is more than just a computer: it's specifically designed for controlling things, and as such ahs a lot of extra parts added on which you would not normally find on a general-purpose computer or CPU/microprocessor. Things like comparators, timers, GPIO (general-purpose input/output) pins, A/D and D/A converters are common on uCs, and these days they frequently have industrial data buses added in too, like CAN (usually used in cars). These of course could all be added to a general-purpose computer, but in a uC, they're all built right onto the chip, and are accessible right at the register level instead of having to communicate over a general-purpose bus to some external module. But if you meant to say that a modern microcontroller is as powerful as a full-fledged "computer" from the 80s, that's definitely true, and really a big understatement as many modern microcontrollers have rather powerful ARM or PowerPC CPU cores and are far more powerful than your typical 1980s microcomputer. uCs these days span an incredible range, from tiny PICs with a few hundred words of flash and a few dozen words of RAM, running at 1MHz, up to very powerful 64-bit SoCs (systems-on-chip) running at well over 1GHz.
