Hello Atieh,
On our LPC43xx, all of our pins are MUX'd to have several functions depending on the ENAIO registers in the SCU. To answer your question, yes you can use either P7_4 or P8_7 as LCD_VD4. I would advise you to plan ahead and look at all pins that can be utilized as LCD data though! There is a chance that not all LCD data bits will be available on more than one pin so be sure to look out for this if you're designing your own custom PCB with an LCD! It'd be an unfortunate unforced error if you designed to use UART0 or LCD_VD4 on the only pin that had LCD_VD16, for example.
