MacBook Pro fans are loud after partitioning disk for Boot Camp use
Is it safe? Yes. 

The 2017 MacBook Pro (13-inch, 2 x Thunderbolt 3 ports) is more than capable of running the latest 64-bit versions of Windows 10 installed with Boot Camp. 

Unfortunately it's difficult for anyone here to speculate on what the Engineer meant, except to say that it seems something has been lost in how they've explained it to you.

However, since Boot Camp is provided by Apple and Boot Camp Assistant software is included with macOS, you know it's safe to use. 

As for your description of the loud sound the fans are making, it's not clear from your question whether your fans are always loud or only when you're trying to do certain things. However, the first thing I'd try is resetting the System Management Controller (SMC).

How to reset the SMC on your particular MacBook Pro


Shut down your MacBook Pro
For 10 seconds, press and hold at the same time the shiftcontroloption keys (on the left side of the built-in keyboard) and the power button
After 10 seconds let go of all keys and the power button 
Turn your MacBook Pro back on with the power button


After your MBP reboots, test to see if the fans are still making the same sound.
