Can I use this pin as a Chip select? And do I need to change settings?

I have an Arduino Unu with an SD card connected to it. For a technical reason, I needed the Chip Selectpin to be another pin than the one used in an example I found on the internet which worked fine.

The original pin was pin 4 and I wanted it to be pin 5.
In my opinion, the pins seem interchangeable, but I have my doubts.

Can pin 5 be a Chipselectpin? Or do I need to make certain changes in order to get that pin working?

Greetings,
Any pin can be used as a chip select(except your MISO and MOSI lines).

Thank you.
I thought the same.
I only have to change the setting from 4 to 5 in the code.
So no other changes like pullups, output assignment or what so ever?

#include <SD.h>

#include <pcmConfig.h>
#include <pcmRF.h>
#include <TMRpcm.h>
#include <SPI.h>

#include "SD.h"
#define SD_ChipSelectPin 5
#include "TMRpcm.h"
#include "SPI.h"
#define next     2
int checker; 

TMRpcm tmrpcm;

void setup(){
tmrpcm.speakerPin = 9;
Serial.begin(9600);
pinMode(next,   INPUT_PULLUP);
if (!SD.begin(SD_ChipSelectPin)) {
 Serial.println("SD fail");

For some reason I have an SD fail message when booting up.
Can that only happen due to errors in that ChipSelectPin connection?
Or also for other reasons, according to the code above.
