Yes and no, is the correct answer, I think.

No, because you can't just directly dd your phone's memory. It doesn't
mount as a block device. Here's the output from dmesg when I attach my
ZTE Axon 7 to my Linux desktop:

[1286610.700895] usb 3-1: new high-speed USB device number 19 using
[1286610.828226] usb 3-1: New USB device found, idVendor=19d2,
[1286610.828231] usb 3-1: New USB device strings: Mfr=1, Product=2,
[1286610.828234] usb 3-1: Product: ZTE USB Device
[1286610.828236] usb 3-1: Manufacturer: ZTE Incorporated
[1286610.828238] usb 3-1: SerialNumber: eef6e35a

However, you can access the phone with adb and fastopen, from a command
terminal. This includes the phone's bootloader and recovery mode, e.g. 

adb reboot bootloader

>From here you can dd any of the phone's partitions, but there are
several, so a tool like twrp might be a better choice.
