Yes but we are already almost two decades in the 21 century https://www.raspberrypi.org/documentation/hardware/raspberrypi/bcm2711/rpi_DATA_2711_1p0_preliminary.pdf https://www.raspberrypi.org/documentation/usage/gpio/ and I am sure if you have the time to write here, you also have the time to check the online documentation. It says that you can power it up with the pins (as before). I just wonder if the current you supply is sufficient. Also it says that powering PI via GPIO bypasses all protection. Here the complete list, if someone is wondering what is needed to bring RPI4B up RPi4 Box Joy-IT with active cooling microSD >=4GB USB charger 3A/5V USB cable (USB-A to USB-C) HDMI cable (HDMI-HDMI micro highspeed)
