Absolutely. The simulator itself would have no problem with this. But it's unclear what you mean by "import". You could create a VHDL view, with the testbench code, and then create a symbol for it and wire it up to the DUT - it's really hard to tell without knowing precisely how you have things structured.
Or you could simulate the code from the command line?

The issue is that without knowing precisely what you're trying to achieve, and how the testbenches are structured, it's very hard to give a precise answer (see the Forum guidelines and Ken's post
